A young Palestinian man with learning disabilities has been shot dead by Israeli troops near the West Bank town of Jenin, Palestinian officials said.
Mujahid al-Simadi, 20, was shot through the chest during a raid to arrest militants.
The Israeli military said its soldiers had seen a 'suspect armed with a weapon who was threatening them'.
A 12-year-old boy was shot dead in the Jenin refugee camp three months ago during a stone-throwing protest.
Local residents said Mujahid al-Simadi had gone up to the troops with a toy gun and shouted that they should leave the village.
He was among a number of children who had surrounded a house occupied by Israeli soldiers and began to throw stones, Palestinian security sources said.
The soldiers opened fire from the house and Mujahid al-Simadi hit in the chest and died immediately, they said.
On Monday, Israeli troops shot and killed a 25-year-old Gaza woman near the border fence between the territory and Israel.
