Three Islamic Jihad terrorists were killed Thursday night in an IAF air strike in Khan Yunis, Hizbullah's Al Manar television reported. Earlier, four terrorists were killed by an IDF tank shell in the act of planting explosives near the perimeter fence in the central Gaza Strip. The incident was not far from where an IDF tracker was killed earlier in the day. On Thursday morning, Palestinian medical officials said an IAF attack on a rocket-launching site in northern Gaza killed a Palestinian operative. The army had no immediate comment. Overnight Wednesday, IDF troops arrested 10 Palestinian fugitives during operations in the West Bank. All of the detainees were transferred to security forces for further interrogation.
