Israel has approved the call-up of about 75,000 army reservists, as it continues its air attacks on the Palestinian group Hamas in Gaza.
The mobilisation is adding to speculation that Israel is preparing to invade the territory to try to stop Palestinian rocket attacks.
The Israeli military says it hit about 200 targets overnight.
