An Israeli missile strike in the northern Gaza Strip killed two people today, Palestinian security services said.
The Israeli military said it had targeted two men suspected of involvement in firing rockets into Israel.
An army spokeswoman said the two 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.
Witnesses said the two were teenage boys who were passing by on bicycles and were hit after stopping to look at the rocket launcher out of curiosity.
Israel has been pressing an offensive in Gaza for the past three months, since militants kidnapped an Israeli soldier in a cross-border operation. The soldier is still being held.
Around 220 Palestinians have been killed in the offensive, around half of them civilians, according to Palestinian medics and research groups.
