Here's the latest on the situation from AlJazeera:
Fresh Israeli air raids have killed at least eight Palestinians in the Gaza Strip and wounded dozens more, medics say, with Palestinian security sources confirming that at least three of the dead were Hamas fighters.
Israel on Saturday expanded its fierce air assault on rocket operations, striking Hamas government and security compounds, tunnels and electricity transformers after an unprecedented rocket attack on Friday aimed at the holy city of Jerusalem raised the stakes.
The Israeli army said that four of its soldiers were injured by a rocket fired from Gaza. Meanwhile, a newly installed battery of Israel's Iron Dome defence system successfully intercepted a Gaza rocket aimed at Tel Aviv on Saturday.
Palestinian medics said 40 Palestinians have been killed and 345 wounded since Israel launched the aerial campaign against the Palestinian enclave on Wednesday.
In the same period, three Israelis have been killed and 18 injured, including 10 soldiers.
Since the start of its operation, Israel's army said it carried out some 700 airstrikes. It also said that fighters have fired more than 580 rockets over the border, 367 of which hit southern Israel, and 222 of which were intercepted by the Iron Dome anti-missile system.
Also now at AlJazeera, breaking news banners read "Israeli air strike hits main gaza police headquarters and prime minister ismail haniyeh's office," and "Israeli cabinet approves plan to call up 75,000 reserve soldiers as air strikes continue on the gaza strip," with no further details as yet.
