Escalating US-Iran Conflict Complicates Israel-Gaza Diplomatic Efforts

Time window: Last 7 days · Audience: General analyst · Type: Situation report · DTG: 2026-07-13 22:29Z · Overall confidence: MEDIUM

BLUF

Very likely the United States and Iran have resumed significant military exchanges following President Trump's 8 July declaration that the ceasefire was 'over,' with CENTCOM confirming strikes against Iranian naval facilities in Bandar Abbas. Almost certainly the Strait of Hormuz is experiencing severe transit disruption as US and Iranian officials provide directly contradictory statements about its operational status, while Gaza continues to endure critical humanitarian conditions with more than 1,000 Palestinians reported killed since the October 2025 peace plan agreement.

Executive summary

US-Iran hostilities have entered a new phase with CENTCOM conducting multiple strikes against Iranian military targets since 8 July, including a submarine maintenance facility in Bandar Abbas, following President Trump's declaration that the ceasefire was 'over.' Iran has responded with attacks against US military facilities in Gulf states including Bahrain, Kuwait, and Jordan. The status of the Strait of Hormuz remains contested, with CENTCOM stating it is open to traffic while Iran declares it closed, causing severe shipping disruption. In Gaza, humanitarian conditions persist with over 1,000 Palestinians reported killed since the October 2022 peace plan, while the Israel-Lebanon ceasefire brokered in April 2026 faces challenges as Hezbollah rejected the 4 June truce deal and demands full Israeli withdrawal.

Change from previous assessment

New development: US and Iran have resumed significant military exchanges following Trump's 8 July declaration that the ceasefire was 'over,' confirmed by US Central Command strikes against Iranian naval facilities in Bandar Abbas and Iranian retaliatory attacks against Gulf states. The Strait of Hormuz dispute has escalated with directly contradictory claims of control, resulting in severe shipping disruption where observable crossings have completely halted. Confirmed addition: UK announced £10 million for UN Horizon Fund and joining EU-led Team Gaza Initiative. Confidence changes: Confidence in Israel-Lebanon ceasefire stability has lowered from medium to high in our assessment of its fragility due to Hezbollah's rejection of the 4 June truce deal.

Key judgments

1. US and Iran have very likely resumed significant military exchanges following President Trump's 8 July declaration that the ceasefire was 'over,' with US Central Command conducting multiple strikes against Iranian military targets including a submarine maintenance facility in Bandar Abbas. (Confidence: high · REPORTED)

• I&W: US Central Command announces additional strikes against Iranian air defence systems within next 48 hours (0-2 days)
• I&W: Iran launches attacks against additional US military facilities in Gulf states within next 72 hours (1-3 days)

2. Almost certainly the Strait of Hormuz is experiencing severe transit disruption as US Central Command asserts the waterway is open to traffic while Iran declares it closed, with observable crossings along the southern corridor having completely halted despite claims of 'secret' transits. (Confidence: high · REPORTED)

• I&W: Zero vessels successfully transiting via AIS within next five days (0-5 days)
• I&W: International Maritime Organization issues urgent navigation warning specifically addressing conflicting claims of control (1-7 days)

3. Very likely more than 1,000 Palestinians have been killed in Gaza since the peace plan agreement signed on 9 October 2025, with UK support for recovery efforts including £10 million for the UN Horizon Fund and participation in the EU-led Team Gaza Initiative. (Confidence: medium · REPORTED)

• I&W: UN reports over 1,200 total Palestinian deaths since peace plan agreement (1-14 days)
• I&W: International Committee of the Red Cross suspends operations due to security concerns (3-10 days)

4. Very unlikely the Israel-Lebanon ceasefire brokered on 16 April 2026 will hold without Hezbollah's withdrawal from areas south of the Litani River, as Hezbollah rejected the 4 June truce deal and demands full Israeli withdrawal from Lebanon. (Confidence: medium · ASSESSED)

• I&W: Hezbollah announces full withdrawal from areas south of Litani River within next week (0-7 days)
• I&W: Israeli Defence Forces announce major cross-border operation entering southern Lebanon (0-3 days)

• I&W: UK Foreign Secretary announces additional funding commitment at Palestine Donor Group meeting (1-10 days)
• I&W: EU officially lists UK as full participant in Team Gaza Initiative operations (7-14 days)

6. Very unlikely Israel will agree to withdraw from Lebanon without Hezbollah first moving its fighters north of the Litani River, as required by the ceasefire agreement. (Confidence: high · REPORTED)

• I&W: Israeli Defence Forces issue public statement conditioning withdrawal on Hezbollah's redeployment (0-3 days)
• I&W: Israeli government rejects UN Security Council Resolution calling for immediate withdrawal (3-7 days)

Outlook & scenarios

Complete Breakdown of Strait of Hormuz Transit (45%)

Iran successfully enforces closure of the Strait of Hormuz through coordinated military action and diplomatic pressure on Oman, causing oil prices to surge above $180 per barrel. The United States responds by deploying additional carrier strike groups to the Persian Gulf while accelerating efforts to establish alternative shipping corridors through the Indian Ocean. Global supply chains face severe disruption as 30% of seaborne oil shipments are rerouted, significantly increasing shipping costs and delivery times for energy-dependent economies.

Temporary Stabilisation Through US-Gulf Mediation (30%)

Gulf Cooperation Council states successfully broker a temporary de-escalation between Washington and Tehran, allowing limited oil shipments to resume through the Strait of Hormuz under joint Omani-US naval escort. The United States agrees to pause further strikes while Iran limits its actions to warnings rather than physical interdiction. This fragile arrangement creates space for renewed talks about formalising secure transit through the strait, though no permanent solution is reached. Oil prices stabilise around $140 per barrel during the interim period.

Expanded Regional Conflict Including Direct Israel-Iran Engagement (20%)

Iran directs Hezbollah to escalate attacks against Israeli positions along the Lebanon border, prompting Israel to conduct direct strikes against Iranian military assets within Lebanon and potentially inside Iran itself. The United States becomes directly involved in combat operations beyond current CENTCOM strikes, potentially engaging Iranian air defence systems with manned aircraft. This expansion of hostilities forces Jordan and Gulf states to fully align with either side of the conflict, effectively ending Saudi-Israeli normalisation efforts that were already in a near-freeze.

Unexpected Political Resolution Through Regional Coalition (5%)

Saudi Arabia, supported by a coalition of Gulf states and European powers, brokers an unexpected political resolution that includes mutual de-escalation between the United States and Iran, a formal guarantee of secure transit through the Strait of Hormuz under international oversight, and a comprehensive package addressing Gaza's reconstruction. This development would represent a major shift in regional dynamics, positioning Saudi Arabia as the primary security broker in the Gulf while marginalising direct US-Iran negotiations. The likelihood is low due to current political configurations but could arise from external pressures such as a global economic crisis triggered by prolonged shipping disruption.

Recommendations

1. Monitor commercial shipping activity through the Strait of Hormuz using AIS data combined with satellite imagery to verify claims about transit levels and assess which vessels are transiting with transponders disabled
2. Track coordination between CENTCOM and Gulf states' naval forces to identify potential flashpoints and early warning indicators of further escalation
3. Analyse patterns of civilian casualty reporting from Gaza through cross-referencing multiple independent medical and humanitarian sources to assess credibility of conflicting claims
4. Assess regional diplomatic initiatives by Gulf states that may emerge as alternatives to US-brokered agreements, particularly regarding transit arrangements through the Strait of Hormuz
5. Monitor Israeli military deployment patterns near the Lebanon border for indications of potential large-scale operations if the ceasefire continues to erode

Confidence & uncertainty

The overall confidence assessment is medium due to strong corroboration on key military events (US-Iran strikes) and diplomatic developments (ceasefire agreements) from multiple independent sources including CENTCOM reports, UK Government statements and major media, but with notable gaps regarding casualty figures where sources vary significantly and low confidence on future strategic intentions. The contradictory claims about the operational status of the Strait of Hormuz reduce confidence in maritime assessments, though the fact of severe disruption is well-supported. Some reporting on Lindsey Graham's activities and death contains conflicting dates that remain unresolved.
