An Israeli attack on the occupied West Bank's refugee camp on Thursday killed nine Palestinians including an elderly woman.
Palestinian officials also said that Israeli forces used tear gas inside a hospital children's ward.
The death toll rose to "nine martyrs including an elderly woman," the Palestinian health ministry said, with at least 16 wounded.
In a separate statement, Palestinian health minister Mai Al-Kaila said that "occupation forces stormed Jenin Government Hospital and intentionally fired tear gas canisters at the paediatric department in the hospital".
She described the situation in the refugee camp as "critical" and said Israeli forces were preventing ambulances from reaching the wounded.
Israel's army declined to comment when asked by AFP about the health minister's tear gas allegation.
The army has said only that its "forces are operating in Jenin".
Thursday's fatalities bring the number of Palestinians killed in the West Bank so far this year to 29, most of whom were shot by Israeli forces.
Jenin deputy governor Kamal Abu Al-Rub told AFP that residents were living in a "real state of war".
"The Israeli army is destroying everything and shooting at everything that moves," he said.
The mounting toll follows the deadliest year in the Palestinian territory since United Nations records began in 2005.
At least 146 Palestinians were killed by Israeli security forces in 2022 in the West Bank and East Jerusalem, according to the Israeli human rights group B'Tselem.
Last year's death toll was the highest since 2004, during the Second Intifada, or Palestinian uprising against the Israeli occupation.
Israel has occupied the West Bank in violation of international law since the 1967 Arab-Israeli War.
The Palestinian presidency said Thursday's raid on Jenin was happening "under international silence".
"This is what encourages the occupation government to commit massacres against our people in full view of the world," said Nabil Abu Rudeinah, spokesman for Palestinian president Mahmud Abbas.
The Palestinian health minister called for an urgent meeting with the World Health Organization and the International Committee of the Red Cross over the events in Jenin.
The latest Israeli massacre comes a day after Israeli forces shot dead two Palestinians in separate incidents.
