Prime Minister Rishi Sunak has urged Iran to cool rising political tensions in the Middle East.
The call came after three US soldiers were killed and 34 injured in a drone-strike on a military base in Jordan.
The losses are the first for America since the Hamas-Israel war began in early October last year.
President Joe Biden has blamed Hamas for the drone attack.
Mr Sunak said:
“We are concerned and would urge Iran to continue to de-escalate tensions in the region.
“We stand resolutely with our allies to bring stability and peace to the region.
“And that’s what we’ll continue to work towards.”
Mr Biden has vowed the US would “respond accordingly” to the weekend assault on its troops.
Iran-backed fighters in eastern Syria have reportedly began evacuating their posts amid fears of retaliatory air strikes.
