US Secretary of State Mike Pompeo said Friday that the US was "committed to de-escalation" after the killing of top Iranian commander Qasem Soleimani in an American strike.
Pompeo tweeted that he had spoken with British Foreign Secretary Dominic Raab, German Foreign Minister Heiko Maas and Chinese Politburo member Yang Jiechi about the killing.
"Thankful that our allies recognize the continuing aggressive threats posed by the Iranian Quds Force," he wrote. "The US remains committed to de-escalation."
The United States announced earlier that it had killed the commander of the Islamic republic's Quds Force in a strike on Baghdad's international airport.
The strike also killed the deputy chief of Iraq's powerful Hashed al-Shaabi paramilitary force.
Pro-Iranian demonstrators laid siege to the US embassy in Baghdad on Tuesday, angered by US weekend air strikes that killed two dozen fighters from the hardline Kataeb Hezbollah paramilitary group.
The strikes were in response to a rocket attack last week that killed an American contractor working in Iraq.
The Pentagon said Soleimani had orchestrated attacks on coalition bases in Iraq over the past few months, including on December 27, the day the contractor was killed.
Soleimani "also approved the attacks" on the US embassy in Baghdad, according to the Pentagon.
