A 19-year-old Palestinian boy has been shot dead by Israeli forces at a refugee camp in the Occupied West Bank, Palestinian medical officials have said.
Two others were injured in the incident, which happened in the Jenin Refugee Camp earlier on Tuesday.
The condition of one of the two injured is serious.
Doctors at a Jenin hospital said Majed Lahlouh was killed with a bullet to his heart. The wounded men also suffered gunshot wounds, they said.
An Israeli military spokesperson had no initial comment.
Eyewitnesses said the Israeli troops entered the narrow streets of the Jenin camp at dawn, apparently seeking to arrest a local resident.
Palestinian youths threw stones at the soldiers, who responded with live gunfire.
Violence in the West Bank has worsened since the beginning of 2013. Israeli forces have killed 11 Palestinians there this year, most of them in clashes, compared with three killed in the same period in 2012, according to United Nations figures.
Last week Israel and the Palestinians resumed US-brokered peace talks after a three-year breakdown although neither side has expressed much optimism for a major breakthrough.
