Palestinian officials say an Israeli air strike has killed a Palestinian man in the Gaza Strip. Officials say the man was killed Sunday. The Israeli military has confirmed carrying out actions in the area.

He is the sixth Palestinian killed in Israeli strikes since Palestinian militants fired a missile at an Israeli military jeep patrolling the border with Gaza Saturday.

Officials and witnesses say 25 people have been wounded in the flare-up, which is one of the most serious clashes in the border region in months.

The armed wing of the Popular Front for the Liberation of Palestine claimed responsibility for firing the anti-tank missile into southern Israel. Four Israeli solders were wounded in the attack.

Sporadic clashes have occurred between Israel and militants in the Hamas-ruled Gaza Strip.

The level of violence in the border region, however, has been down significantly since an Israeli military operation in the region in 2008 killed 1,400 Palestinians.
