Israelis and Palestinians trade fire after deadly West Bank raid

Gaza militants fired rockets and Israel carried out airstrikes early Friday as tensions soared following an Israeli raid in the occupied West Bank that killed nine Palestinians, including at least seven militants and a 61-year-old woman.

It was the deadliest single raid in the territory in over two decades. The flare-up in violence poses an early test for Israeli Prime Minister Benjamin Netanyahu's far-right government and casts a shadow on U.S. Secretary of State Antony Blinken's expected trip to the region next week.

Palestinian militants fired five rockets at Israel, the military said. Three were intercepted, one fell in an open area and another fell short inside Gaza. Israel carried out a series of airstrikes at what it said were militant targets. There were no immediate reports of casualties.

Thursday's deadly raid in the Jenin refugee camp was likely to reverberate on Friday as Palestinians gather for weekly Muslim prayers that are often followed by protests. Hamas, the Islamic militant group that controls Gaza, had earlier threatened revenge for the raid.

Raising the stakes, the Palestinian Authority (PA) said it would halt the ties that its security forces maintain with Israel in a shared effort to contain Islamic militants. Previous threats have been short-lived, in part because of the benefits the authority enjoys from the relationship and also due to U.S. and Israeli pressure to maintain it.

The Palestinian Authority already has limited control over scattered enclaves in the West Bank, and almost none over militant strongholds like the Jenin camp. But the announcement could pave the way for Israel to step up operations it says are needed to prevent attacks.

Hamas, the Islamic militant group that controls Gaza, had earlier threatened revenge for the raid. Violent escalations in the West Bank have previously triggered retaliatory rocket fire from the Gaza Strip, which in turn has brought Israeli airstrikes down on the isolated and impoverished territory.

The Israeli strikes early Friday targeted training sites for Palestinian militant groups, the military said. Witnesses and local media reported that Israeli drones fired two missiles at a Hamas militant base before fighter jets struck it, causing four large explosions.

Air raid sirens went off in southern Israel as the initial two rockets were fired and then again after the airstrikes, when the militants fired the other three rockets.

On Thursday, Israeli forces went on heightened alert as Palestinians filled the streets across the West Bank, chanting in solidarity with Jenin. Palestinian President Mahmoud Abbas declared three days of mourning, and in the refugee camp, residents dug a mass grave for the dead.

Palestinian Authority spokesperson Nabil Abu Rudeineh said Abbas had decided to cut security co-ordination in "light of the repeated aggression against our people, and the undermining of signed agreements," referring to commitments from the Oslo peace process in the 1990s. He also said the Palestinians planned to file complaints with the UN Security Council, International Criminal Court and other international bodies.

The PA last cut security co-ordination with Israel in 2020, over Netanyahu's drive to annex the occupied West Bank, which would make a future Palestinian state all but impossible.

But six months later, the PA resumed co-operation, signaling the financial importance of the relationship and the Palestinians' relief at the election of U.S. President Joe Biden.

Barbara Leaf, the top U.S. diplomat for the Middle East, said the administration was deeply concerned about the situation and that civilian casualties reported in Jenin were "quite regrettable." But she also said the Palestinian announcement to suspend security ties was a mistake.
