(Reuters) - Israeli tank fire killed four Palestinians in the Gaza Strip on Saturday after militants blew up an Israeli army jeep with an anti-tank missile, wounding four soldiers.
Palestinian fighters retaliated by firing rockets into southern Israel and an Israeli air strike targeted a rocket crew, killing a Palestinian militant, the Israeli army said.
The flareup carried the risk of further escalation. Explosions were audible and projectiles lit up the sky over Gaza shortly before midnight, but no further details were immediately available.
Palestinian militants vowed to take revenge for the deaths of the four civilians and the 25 wounded. Israel warned residents of communities near the Gaza border to stay within 15 seconds of their blast shelters in case of a rocket salvo.
