Islamic Hamas movement and its armed wing al-Qassam Brigades on Friday accused the Israeli security intelligence of killing one of its top senior military leaders in Dubai. Izzat al-Resheq, Islamic Hamas movement politburo member, told a Hamas news website that Israel was behind the killing of top Hamas movement militant Mahmoud al-Mabhouh in Dubai on Jan. 20. Al-Mabhouh, originally from the Hamas-ruled Gaza Strip, is the founder of the Islamic movement's armed wing known as Izzedein al- Qassam Brigades at the beginning of the first Palestinian Intifada, or Uprising, in 1988. Israel accused him of being behind the kidnapping and killing of two Israeli soldiers in Gaza in 1988. Most of those involved in the incident were either detained or killed by Israel, including Hamas founder and spiritual leader Sheikh Ahmed Yassin, who was killed in 2004. Since 1988, al-Mabhouh had fled the Gaza Strip and has been living abroad, mainly in Damascus, until he died in a hospital as he was secretly visiting in Dubai. Meanwhile, al-Qassam Brigades in Gaza said in a leaflet sent to reporters that it mourns al-Mabhouh's death and vowed to revenge his assassination.
