Washington • Multiple American citizens were killed and injured in the Taliban’s 13-hour siege of an upscale hotel in Kabul, Afghanistan, the State Department said Tuesday.

No exact figures were immediately available for either the U.S. fatalities or injuries. In total, 22 people were killed in the attack including 14 foreigners, Afghan officials have said. Eleven of the 14 foreigners had been previously identified as working for the private Afghan airline KamAir.

“We offer our deepest condolences to the families and friends of those who were killed and wish for the speedy recovery of those wounded,” the State Department said. “Out of respect for the families of the deceased, we have no further comment.?”

The American deaths were the latest reminder of the continuing toll paid by the United States in Afghanistan, where local forces have struggled to fight the Taliban since the U.S. and NATO formally ended their combat mission in 2014.

President Donald Trump has pursued a plan that involves sending thousands more U.S. troops to Afghanistan and envisions shifting away from a “time-based” approach to one that more explicitly links U.S. assistance to concrete results from the Afghan government. Trump’s U.N. envoy, Nikki Haley, said after a recent visit to Afghanistan that Trump’s policy was working and that peace talks between the government and the Taliban are closer than ever before.

The six Taliban militants who stormed Kabul’s Intercontinental Hotel on Saturday in suicide vests were looking for foreigners and Afghan officials to kill. Afghan security forces have said the standoff ended Sunday when they killed the last of the militants. More than 150 people were rescued or escaped during the siege, including 41 foreigners. Some hid in bathtubs or under mattresses as the attackers roamed the hotel’s hallways killing people.

It was unclear how seriously the injured Americans were wounded. In addition to the Americans killed in the attack, six Ukrainians, two Venezuelan pilots for KamAir and a citizen of Kazakhstan and a citizen of Germany were also killed, officials have said.
