Israel continued to blast targets in the Gaza Strip Sunday, launching aerial and naval attacks in response to continuing Palestinian rocket fire.

Three Arab journalists were wounded when an Israeli air strikes hit an Arab media office Sunday.

Palestinian officials said more than 48 Gazans have been killed since the campaign began Wednesday.

On Saturday, Israeli strikes leveled the Gaza office of Hamas Prime Minister Ismail Haniyeh and his Cabinet. Haniyeh was not there at the time.

Also Saturday, Egyptian President Mohammed Morsi hosted leaders from Hamas and two key allies, Qatar and Turkey, to seek a way to end the fighting. He said “there are some indications that there is a possibility of a cease-fire soon, but we do not yet have firm guarantees.''

Separately, foreign ministers from the Cairo-based Arab League were meeting in emergency session to discuss an Arab response to the fighting.

More than 100 Hamas rockets rained down on Israel Saturday, reaching as far north as Tel Aviv where sirens wailed early in the day.

Israel's military says its new “Iron Dome” missile defense system shot down an incoming rocket bound for Tel Aviv – one of several Hamas has fired at Israel's commercial center.

Israel says “Iron Dome” has intercepted nearly 250 Hamas rockets fired this past week.
