Rocket-warning sirens sound in Tel Aviv as Hamas says it has launched 130 rockets on Israel in response to the strikes on tower building in Gaza.
The Israeli military has continued its bombardment of the besieged Gaza Strip early on Wednesday, targeting several areas after rockets were fired from the enclave.
It is the most intense airstrikes in Gaza since the bombardment in 2014
Health authorities in Gaza said at least 35 Palestinians – including 10 children – were killed in Israeli air strikes on the Strip since late on Monday, after Hamas launched rockets from the coastal territory towards Israel.
At least three Israelis have also been killed.
The rocket fire came after Hamas, which rules Gaza, issued an ultimatum demanding Israel stand down its security forces from the Al-Aqsa Mosque compound in occupied East Jerusalem after days of violence against Palestinians.
Israeli police stormed the compound on Monday for a third consecutive day, firing rubber-coated steel rounds, stun grenades and tear gas at Palestinian worshippers inside the mosque in the final days of the holy month of Ramadan.
