About 76,000 nationals thought to be in the region as tensions rise after US-Israeli attacks on Iranian regime

US-Israeli war on Iran: latest updates

The Foreign Office is drawing up plans to evacuate tens of thousands of British citizens if war in the Middle East escalates, with many travellers currently stranded in Dubai.

The government does not know how many British nationals are resident, on holiday or otherwise travelling across the Gulf, but it said 76,000 have so far registered their presence in affected areas of the region.

More than 50,000 of those are believed to be in the United Arab Emirates, and most of those are holidaymakers or other travellers, rather than residents, with Dubai a major tourist and business destination. Its airspace is currently closed, leaving tourists without a plan for getting home.
