GAZA CITY, Sept 5 (AP/UNB) - Gaza security officials say an Israeli airstrike targeting a smuggling tunnel has killed one Palestinian, wounded a second and left three more missing.

The Hamas officials identified the five as smugglers working in the tunnel under the Gaza-Egypt border.

They spoke Sunday on condition of anonymity because authorities had not officially released the information. The Israeli military said aircraft attacked tunnels in retaliation for Hamas shooting attacks against Israelis in the West Bank over the last week.

The Hamas attacks killed four settlers and wounded two others. They took place as Israelis and Palestinians relaunched direct peace negotiations in Washington.
