Three U.S. service members killed in Afghanistan blast

Three U.S. service members were killed and three wounded when an improvised explosive device detonated on Tuesday near the central Afghan city of Ghazni, the NATO-led Resolute Support mission said in a statement.

A U.S. civilian contractor was also wounded in the blast and was receiving treatment with the other wounded, the statement said, giving no further details.

The city was overrun by a large Taliban force earlier this year before being driven off by Afghan and U.S. forces after days of heavy fighting.
