RAMALLAH, West Bank, June 3 (Reuters & JMCC) - Israeli troops on Tuesday shot dead a Palestinian who the military said had opened fire and wounded a soldier at a checkpoint in the occupied West Bank.

The Palestinian mainstream Fateh group identified the man as Alaa Odeh, a 30-year-old mobile phone shop owner, and along with relatives accused soldiers of killing him in cold blood.

In a statement, the military said a Palestinian gunman opened fire and wounded a border policemen, and the force returned fire, killing the perpetrator.

It posted on Twitter a photograph of a pistol on the ground and said the attacker had fired six shots. Odeh's family was quoted as saying in media reports that he was at the checkpoint awaiting a delivery of phones.

The night-time incident came hours after Palestinian President Mahmoud Abbas swore in a new unity government, healing a rift with Hamas Islamists in Gaza, and raising tensions with Israel.

The shooting occurred at the Zaatara checkpoint on the way to Nablus city where troops, four days ago, arrested a Palestinian who the military said was wearing an explosives belt.

U.S.-led peace talks between the Israelis and Palestinians collapsed in April and some analysts have warned of a possible spike in violence given the lack of any clear way forward to resolve the generations-old conflict.
