An American woman has been shot dead in the occupied West Bank during a protest.
Aysenur Ezgi Eygi, 26, who was also a Turkish citizen, is said to have been taking part in a protest against Jewish settlement expansion in the town of Beita near Nablus.
Local media reported the activist was shot by Israeli troops.
The Israel Defense Forces (IDF) said they are aware of an incident and were looking into it, the BBC reported.
Ms Ezgi Eygi was rushed to a hospital in Nablus with a gunshot wound to the head and was later pronounced dead, AFP news agency reported.
US Ambassador to Israel Jack Lew confirmed to CNN she was the victim, and said the US was “urgently gathering more information about the circumstances of her death.”
The White House said in a statement it was "deeply disturbed" by the killing of a US citizen.According to reports by Palestinian media, the 26-year-old had been involved in a campaign to protect farmers from Israeli settler violence.
She was attending a weekly demonstration against settlement expansion, protests that have grown violent in the past.
A month ago, American citizen Amado Sison was shot in the leg by Israeli forces, he said, as he tried to flee tear gas and live fire.
It comes as Israeli forces appeared to have withdrawn from Jenin and two other refugee camps in the occupied West Bank after a nine-day military operation in which dozens were killed.
Overnight on Thursday, Israeli armoured personnel carriers were seen leaving the Jenin refugee camp from a checkpoint set up on one of the main roads.
An Associated Press reporter inside the camp saw no evidence of any remaining troops inside as dawn broke early on Friday morning.
During the operation, Israeli military officials said they were targeting militants in Jenin, Tulkarem and the Al-Faraa refugee camps in an attempt to curb recent attacks against Israeli civilians they say have become more sophisticated and deadly.
Troops were pulled out of the Tulkarem camp by Friday morning and had left Al-Faraa earlier, but in a statement the Israeli military suggested the operation was not yet over.
"Israeli security forces are continuing to act in order to achieve the objectives of the counterterrorism operation," the military said in a statement.
Hundreds of Israeli troops have been involved for more than a week in what has been their deadliest operation in the occupied West Bank since the Israel-Hamas war began, employing what the United Nations called "lethal war-like tactics."
The main focus has been the Jenin refugee camp, a stronghold of Palestinian militancy that has grown since the Hamas attack on Israel that started the war in Gaza nearly 11 months ago.
Fighting in Jenin accounts for 21 of 39 Palestinians who local health officials say have been killed during the Israeli push in the West Bank — most of whom, the military says, have been militants.
The fighting has had a devastating effect on Palestinian civilians living in Jenin.
Water and electric services have been cut, families have been confined to their homes and ambulances evacuating the wounded have been slowed on their way to nearby hospitals, as Israeli soldiers search for militants.
During the operation, Israeli forces sent military bulldozers into the camp, ripping up roads in search of buried explosives.
When asked by an Associated Press reporter about the infrastructure damage caused to the Jenin camp, an Israeli military official acknowledged the destruction but said it was a result of a militant strategy planting explosives in civilian areas. The official spoke on condition of anonymity in line with military regulations.
In the quiet morning on Friday, Jenin residents took advantage of the lull to rummage through the rubble of destroyed buildings and take stock of the damage.
Twisted rebar protruded from the concrete of collapsed buildings, and walls still standing were pockmarked by bullets and shrapnel, an Associated Press journalist reported.
In the Tulkarem camp, resident Ziad Abu Tahoun looked with dismay at the torn up streets and crumbled buildings all around him.
"Look at the condition of the camp, the camp is in a deplorable state," he said. "They've set us back 60 years."
In southern Gaza, health workers resumed vaccinating children against polio, continuing the second phase of a large-scale immunisation campaign.
Children lined up early on Friday morning outside a United Nations health center in Khan Younis to receive the vaccine, which was being administered by local health care crews in coordination with UNICEF and the World Health Organization.
The first phase started on Sunday in hospitals and medical locations in the central Gaza Strip. The final phase was to focus on the north, finishing September 9.
The operation was undertaken as an urgent measure to prevent a large-scale polio outbreak after health officials confirmed the first reported polio case in 25 years, in a 10-month-old boy who is now paralysed in the leg.
