Washington: A fourth US soldier has died as a result of a roadside bomb attack in Afghanistan last week, the Pentagon said.
Sergeant Jason Mitchell McClary , 24, from Pennsylvania, died on Sunday, after being treated in a US military hospital in Germany, the Pentagon said in a statement.
His death takes the number of American military personnel to have been killed in Afghanistan this year to 13.
The November 27 attack saw an improvised explosive device (IED) detonated near Ghazni city in central Afghanistan.
Two other US troops and an American contractor were wounded in what was the deadliest single incident for US forces so far this year.
