The Pentagon on Sunday afternoon announced that a seventh U.S. service member died after he was seriously wounded last week in the widening conflict.

March 8 (UPI) -- The Pentagon on Sunday afternoon announced that a seventh U.S. service member has died during the U.S. and Israeli conflict with Iran.

The service member was seriously wounded during an attack on U.S. troops in Saudi Arabia on March 1, military officials said.

"Last night, a U.S. service member passed away from injuries received during the Iranian regime's initial attacks across the Middle East," U.S. Central Command said in a post on X.

"Major combat operations continue. The identity of the fallen warrior will be withheld until 24 hours after next of kin notification," CENTCOM said.

The seven service members have been killed during the first week of Operation Epic Fury, which the United States and Israel launched on Feb. 28.

Since the beginning of the onslaught, Iran has launched retaliatory strikes at its neighbors, some of which host U.S. bases and assets that are being used in the war.

A March 1 retaliatory strike on an Army sustainment unit based in Kuwait killed six service members and injured 18 others, whose remains returned to the United States on Saturday.

Overall, Iran's retaliatory strikes have killed at least 20 people across the region, The New York Times reported, while between 800 and 1,300 hundred people in Iran have died during the widening conflict.
