Israeli troops shot and wounded three Palestinians, one of them seriously, and blew up what they said was a bomb-making factory during an ongoing operation in the Nablus refugee camp of Balata, medics and security sources said.
One of the Palestinians, shot in the chest and stomach, was hospitalised after he and the two others were fired on as they threw stones at soldiers.
On Monday, the second day of the Israeli incursion into Balata, 17 Palestinians were wounded.
An Israeli army spokeswoman said troops found overnight a ‘laboratory containing materials and explosives for making bombs’ and blew it up.
Also on Tuesday, Israeli forces arrested 11 militants, including six from Hamas, which won last month's Palestinian elections, and four from its smaller rival, Islamic Jihad.
