Israel launched a provocative army raid on a West Bank refugee camp today - the second such unilateral operation this week.
Palestinian officials said undercover troops entered the Jenin camp before dawn, searching for an alleged terrorist.
The incursion on Palestinian land ignited a mass protest. The Israeli military said "around 500" Palestinians threw stones and firebombs at troops. Others burned tyres in the streets.
Troops left the camp after realising the man they wanted to arrest was not at home. Three Palestinians were injured in the operation, with one man shot in the hand, one in the leg and an elderly woman bitten by an army dog.
Israel usually co-ordinates its "security" operations in the Occupied Territories with Palestinian authorities but since Palestine's successful bid for non-member status at the United Nations it has increasingly launched surprise raids.
A raid by soldiers in disguise on the village of Tamoun on Tuesday injured over 100 Palestinians.
