Trump says US 'will retaliate' after three Americans killed in Syrian 'Islamic State attack'

Donald Trump has said the US "will retaliate" after three Americans were killed in a suspected Islamic State attack in Syria.

Two US service members and one civilian died and three other people were injured in an ambush on Saturday by a lone IS - also often called ISIS in Syria and Iraq - gunman, according to the he US military's Central Command. The attack on US troops in Syria is the first to inflict fatalities since the fall of President Bashar Assad a year ago.

"This is an ISIS attack," the US president told reporters at the White House before leaving for the Army-Navy football game in Baltimore. He paid condolences to the three people killed and said the three others who were wounded "seem to be doing pretty well".

In a post on his Truth Social platform, Mr Trump said "there will be very serious retaliation". The shooting took place near historic Palmyra, according to the state-run SANA news agency, and the casualties were taken by helicopter to the al Tanf garrison near the border with Iraq and Jordan.

The UK-based Syrian Observatory for Human Rights said the attacker was a member of the Syrian security force. Syria's Interior Ministry spokesman Nour al Din al Baba said authorities are looking into whether the gunman was an IS member or only carried its extreme ideology, and denied reports suggesting he was a security member.

Pentagon chief spokesman Sean Parnell said the civilian killed in the attack was a US interpreter.

US defence secretary Pete Hegseth posted on X: "Let it be known, if you target Americans - anywhere in the world - you will spend the rest of your brief, anxious life knowing the United States will hunt you, find you, and ruthlessly kill you." The US has hundreds of troops deployed in eastern Syria as part of a coalition fighting IS. The group was defeated on the battlefield in Syria in 2019 but the UN says the group still has between 5,000 and 7,000 fighters in Syria and Iraq, and its sleeper cells still carry out deadly attacks.

Syria's interim president, Ahmad al Sharaa, made a historic visit to Washington DC last month as Syria signed a political cooperation agreement with the US-led coalition against IS. "This was an ISIS attack against the US, and Syria, in a very dangerous part of Syria, that is not fully controlled by them," Mr Trump said in his social media post, adding that Mr al Sharaa was "extremely angry and disturbed"..
