WASHINGTON (AP) -- President Donald Trump is heading to Dover Air Force Base to pay tribute to the four Americans killed in a suicide bomb attack in Syria this week.
He tweets: "Will be leaving for Dover to be with the families of 4 very special people who lost their lives in service to our Country!"
The Delaware trip hadn't been on the president's public schedule for Saturday, but he tweeted the news before he left the White House.
The bombing in Manbij was the deadliest assault on U.S. troops in Syria since American forces moved into the war-torn country in 2015.
The attack came about a month after Trump said the Islamic State group had been defeated and he was withdrawing U.S. forces from the country.
ISIS claimed responsibility for the attack.
