Two people have been killed in an Israeli missile strike in the northern Gaza Strip, Palestinian security officials say.

The Israeli military said it had targeted men suspected of involvement in firing rockets into Israel.
Witnesses said the two men were killed in a street in the town of Beit Hanoun.
Israel launched its latest offensive in Gaza in late June, after Palestinian militants based there captured an Israeli soldier in a cross-border raid.
The Israeli campaign in Gaza aims to secure the release of the captured soldier and stop Palestinian militants firing rockets into Israel.
An Israeli army official said the two Palestinians had been hit as they were collecting a rocket launcher that had been used several times over the past week to fire rockets from northern Gaza.
Palestinian witnesses said the two victims were teenage boys who were passing by on bicycles and were hit after stopping to look at the rocket launcher, the Reuters news agency reported.
More than 230 Palestinians have been killed by Israeli forces since the end of June 2006.
About half of those killed were civilians or not taking part in any hostilities at the time of their death, Palestinian medics and an Israeli human rights group have said.
