Suicide Attack at Israel-Gaza Border.

A suicide bombing at a border crossing between Israel and Gaza has claimed several casualties.

Militant group Hamas says it was behind the attack that injured at least 13 Israeli soldiers.

Cars were blown up by Palestinian militants in the raid on the Kerem Shalom crossing in the Gaza Strip, a territory controlled by Hamas.

Up to four Palestinian activists were killed in the explosions and exchanges of fire.

Timed to coincide with the start of the Jewish Passover today, Israel's army believes one aim of the attack may have been the abduction of Israeli troops.

Israel has stepped up security in the run-up to the Passover holiday, amid fears of increased violence.

A statement from Israel's military said West Bank and Gaza crossings were being closed until the end of the Passover holiday on April 26.
