Six people were wounded, including one critically, in a Palestinian terrorist shooting attack targeting the “tunnels” checkpoint on the West Bank’s Route 60, south of Jerusalem, police and medics said Thursday morning.

Police said the car in which the terrorists arrived had false license plates, and identified two of them as Palestinians from the Hebron area. The Shin Bet security agency later named the two as Hamas member Abdelqader Qawasmeh, 26, and 28-year-old Hassan Qafisha, who is affilated with Hamas and whose father was the head of the terror group’s military arm in Hebron until he was killed in 2003. The identity of the third gunman was still under investigation.

Police Commissioner Kobi Shabtai, who arrived at the scene, said this indicated that they had planned a much larger-scale terror “massacre” inside Jerusalem.
