Iran live updates: 7th killed service member is identified

The seventh service member to die from Iranian attacks has been identified by the Defense Department as Sgt. Benjamin N. Pennington, 26, of Glendale, Kentucky.

Pennington was wounded on March 1 when his base in Saudi Arabia was attacked. He died from his injuries on Sunday, the Defense Department said.

Pennington was at a strategic radar site that's part of the early warning systems for missile defense, according to a source familiar with the situation.

The Israeli military said it had begun on Monday a "targeted and limited" raid in southern Lebanon, where it says it's targeting Hezbollah infrastructure.

"Prior to the entry of ground forces, numerous terror targets were struck from the air and ground," the Isreal Defense Forces said on social media.

"This operation aims to strengthen forward defensive positions and provide an additional layer of protection for residents of northern Israel," the military added.

Two men were in serious condition in Israel after an Iranian missile attack targeted the center of the country, Magen David Adom, the Israeli emergency response organization, said in Hebrew in on social media.

"In another incident in the center of the country, Magen David Adom medics and paramedics are providing medical treatment and evacuating a man approximately 30 years old in serious condition with shrapnel injuries to Sheba Medical Center, Tel Hashomer," the organization said in an update on social media.

The Israel Defense Forces said in an update that its personnel were responding to the impact sites.

The State Department on Sunday ordered the evacuation of non-emergency government employees and their families from Saudi Arabia, updating earlier guidance that authorized them to depart due to safety risks. Saudi Arabia remains a Level 3 "Reconsider Travel" country for U.S. citizens.

The U.S. embassy in Saudi Arabia remains operational with core staff in place, according to the State Department.
