(Updated Wednesday 9:30AM) Two Jenin region terrorist kingpins were killed last night when an explosion went off inside the building where the two were meeting. While Israel has yet to comment on the incident, one Arab eyewitness claimed that the men died when an IDF helicopter gunship fired a pinpointed missile at their position. Another said that there were no helicopters in the sky, but that simply a bomb went off inside the building. The two Arabs were identified as Allah al-Sabbag, the Al Aksa Brigade leader in the area, and Imad Nashrati, a top Hamas member. Both were on Israel's most wanted list. IDF forces had entered the Jenin area several hours prior to the incident.
