Israeli soldiers killed at least 10 people during a raid on a refugee camp in the West Bank on Saturday, Israel’s military said. It’s the latest deadly assault in the long-running conflict there that has only become worse during the six-month war between Israel and Hamas in the Gaza Strip.

The latest violence prompted the Fatah party, which dominates the Palestinian Authority, to declare a general strike across the West Bank on Sunday in protest, with support from the Palestinian teachers and transit worker unions. The region’s government services, schools and educational facilities are expected to shutter for the day.

The Israeli military said that 10 Palestinians had been killed and eight people were arrested during what it called a “counterterrorism operation” at the Nur Shams refugee camp in Tulkarem. Soldiers also raided a compound where explosives were stored and then destroyed or confiscated weapons, the military said. The Israeli military said the 10 killed were militants, a claim that could not be immediately verified.

The Palestinian Health Ministry in the West Bank confirmed that at least 13 people including a 15-year-old, have been killed with several more wounded during the clashes in the area, which have been going on since Thursday evening.

Violence in the occupied West Bank has sharply escalated since the Hamas-led attacks on Israel on Oct. 7. Across the West Bank and in East Jerusalem, more than 400 Palestinians have been killed by Israeli forces since the start of the war, according to the United Nations. Many were killed during near-daily Israeli military raids in Palestinian cities and towns, while others had carried out or attempted attacks on Israelis.

There were clashes elsewhere on the West Bank on Saturday.

Yesh Din, an Israeli rights group that tracks Jewish extremist violence in the West Bank, reported that a Palestinian Red Crescent ambulance had been fired at while responding to armed settler attacks in another town farther south, Al-Sawiya.

It was unclear who fired at the ambulance, but the 50-year-old paramedic who was driving the vehicle, Mohammed Awad Allan, was killed while treating injured people, the Palestinian Health Ministry and the Palestinian Red Crescent said.

Mustafa Taqatqa, the Palestinian Authority governor in the Tulkarem area, said residents there were “seeing violence and destruction like there is in Gaza.” He said that Israeli military patrols had also deployed outside the Nur Shams refugee camp — the focus of the raid.

“There are very few people out in the streets, and a feeling of danger is everywhere,” Mr. Taqatqa said.

Israeli tractors and heavy vehicles had torn some streets in and around the refugee camp, he said. Municipal officials had just finished repaving a major road damaged in another recent Israeli raid, only for Israeli tractors to damage it once again when the military operation began on Thursday night, Mr. Taqatqa said.

The Palestinian Authority has also sought to crack down on armed militants and has worked closely with Israeli security forces to arrest them, a policy known as security coordination. Mr. Taqatqa said that shortly before the raid, militants and Palestinian security forces had clashed in the city of Tulkarem over what he called a “misunderstanding.” He declined to provide further details.

“But in Nur Shams, it’s not just militants,” he said. “There are civilians in the line of fire, all the residents of this refugee camp. We feel that everyone is facing an unrestrained assault.”
