Three Palestinians were killed on Monday in the occupied West Bank in two separate clashes with the Israeli army, the Palestinian health ministry said.
Two Palestinians in their 20s were killed in an Israeli army operation in Dura, in the southern West Bank, witnesses told an AFP journalist.
They described seeing young Palestinians throwing stones and hearing gunshots.
"All of a sudden, soldiers arrived in our town and started shooting at people without any warning," Mohammed Rabaei, head of Dura hospital, told AFP.
Nine people were wounded in the violence, including four left in a critical condition, according to the health ministry.
The Israeli army did not immediately respond to a request for comment.
In the north, in Tulkarm province, another Palestinian was killed, according to the health ministry.
Since the start of the Israel-Hamas war in Gaza on October 7, the West Bank has experienced a level of violence not seen since the Second Intifada, between 2000 and 2005.
Israeli army raids and attacks by settlers have killed around 340 people in the West Bank since then, according to an AFP tally based on sources from both sides.
Separately, Israel arrested students at a university in the occupied West Bank in an early morning raid on Monday because of their alleged support for Hamas, sources on both sides said.
The students attended An-Najah National University in Nablus, which called for their immediate release and labelled the army raid a "blatant Israeli aggression".
The university and the Palestinian Prisoners' Club, a campaign group, said 25 students had been arrested in the raid.
The Israeli army said only that security forces had arrested "nine wanted persons associated with a Hamas student cell".
A Palestinian security source, speaking on condition of anonymity, said the arrests came after the students held prayers for Hamas and praised the Islamist militant group on social media.
The Palestinian security source said it was clear "the occupation (Israel) is launching a campaign against everything related to supporting the resistance in Gaza".
More than 520 Palestinians were killed in the West Bank in 2023, according to the Palestinian health ministry.
Over the same period, Palestinian militants carried out attacks in Israel and the West Bank that killed at least 41 people, according to the Shin Bet security agency.
Israel has occupied the West Bank, home to about three million Palestinians, since the Six-Day War of 1967.
Excluding annexed east Jerusalem, the territory is now home to around 490,000 Israelis who live in settlements considered illegal under international law.
UN chief calls for 'immediate' ceasefire in Gaza
UN Secretary-General Antonio Guterres called Monday for an "immediate humanitarian ceasefire" in the Gaza Strip, as the fighting between Israel and Hamas passed the 100-day milestone.
"We need an immediate humanitarian ceasefire. To ensure sufficient aid gets to where it is needed. To facilitate the release of the hostages. To tamp down the flames of wider war because the longer the conflict in Gaza continues, the greater the risk of escalation and miscalculation," Guterres said at a press briefing in New York.
The war, sparked by a Hamas surprise attack on Israel, has created a humanitarian catastrophe for the 2.4 million people in the besieged strip, the United Nations and aid groups warn, and reduced much of the territory to rubble.
Hamas's October 7 attack that triggered the fighting resulted in about 1,140 deaths in Israel, mostly civilians, according to an AFP tally based on official Israeli figures.
The militants also seized about 250 hostages, 132 of whom Israel says remain in Gaza, including at least 25 believed to have been killed.
Vowing to destroy Hamas, Israel launched a relentless military campaign that has killed at least 24,100 people in Gaza, mostly women and children, according to the Hamas government's health ministry.
The UN says more than three months of fighting have displaced roughly 85 percent of the territory's population, crowded into shelters and struggling to get food, water, fuel and medical care.
Guterres condemned a humanitarian situation in Gaza that he said was "beyond words."
The "vast majority" of the UN's Palestinian staff have fled their homes and 152 staff members have been killed since October 7, Guterres said -- "the largest single loss of life in the history of our organization."
With aid deliveries struggling to get through to a "traumatized people," Gaza now faces "the long shadow of starvation."
"Nothing can justify the collective punishment of the Palestinian people," Guterres said.
The UN leader also warned about what he said was escalating spillover of the conflict, including across the Lebanon-Israeli border. "This risks triggering a broader escalation... and profoundly affecting regional stability," he said.
