Renewed violence in Gaza threatened to thwart efforts to end months of unrest as Israeli air strikes killed three Palestinians and destroyed a Hamas TV building while a barrage of rocket fire from the enclave left one dead on Tuesday. The flare-up came after a deadly Israeli special forces operation in the Gaza Strip on Sunday that led Hamas to vow revenge. Israel’s military said it had so far struck more than 70 militant sites in response to over 300 rockets fired from the Hamas-run territory Monday afternoon into the night. Missile defences intercepted dozens of rockets from Gaza and most others fell in open areas, though some hit houses and other civilian structures, the military said.

Medics had earlier reported around 20 Israelis wounded, while Gaza’s health ministry said three Palestinians were killed and nine wounded in the Israeli strikes. Militant group the Popular Front for the Liberation of Palestine said two of those killed were its members and the third was from Islamic Jihad’s armed wing.

Before the flare-up, Prime Minister Benjamin Netanyahu had defended his decision to allow Doha to transfer the cash despite criticism from within his own government, saying he wanted to avoid a war if it was not necessary. Israel and Palestinian militants in Gaza have fought three wars since 2008, and deadly clashes in recent months have raised fears of a fourth.
