The UN Security Council has called for a ceasefire between Israel and the Palestinians in the Gaza Strip, as Palestinian deaths continue to mount.

An air strike on Gaza City on Saturday killed 15 people, local officials say, with Gaza’s police chief among those injured.

At least 156 Palestinians have been killed since Israel began its operation five days ago, Palestinian sources say.

Israel said it had been hit by about 90 rockets fired from Gaza on Saturday.

It also reported intercepting three rockets fired at Tel Aviv from the coastal territory by Hamas Islamist militants, while other rockets fired from Gaza reached the West Bank.
