Six Palestinians have been killed in an Israeli army raid in Jenin refugee camp in the occupied West Bank, the Palestinian health ministry has said.
The raid on Tuesday afternoon took place in a refugee camp which is a frequent target for Israeli operations against Palestinian militants.
There were reports of heavy exchanges of gunfire, while videos on social media showed smoke billowing from a building and helicopters flying over a long line of military vehicles.
The Palestinian health ministry listed the dead as five men in their 20s and one man of 49, identified as Abdel Fattah Kharousha.
A spokesman for the Palestinian presidency, Nabil Abu Rudeineh, said the Israeli government was responsible for "this dangerous escalation", accusing it of waging "all-out war".
