Hamas -- the Palestinian militant group whose history of violence toward Israel landed it on the United States' terror list -- seems to be dealing with its own terrorism problem.
The commander of Hamas' armed wing recently penned an urgent letter to Hamas leadership in Damascus lamenting what he called Hamas' "deteriorating" authority in the Gaza Strip.
In the dispatch, Ahmed Ja’abri claims that Hamas is losing control over the territory, according to reports by London-based Arab-language newspaper Asharq Al-Awsat quoted by the Jerusalem Post.
"Several worrisome explosions recently occurred in Gaza, security anarchy is extensive, and al-Kassam men are being killed," Ja'abri said in the letter, according to reports.
The letter comes after a series of assassinations and explosions near the offices of senior Hamas military commanders and of Hamas prime minister, Ismail Haniyeh, according to the Jerusalem Post. No individual or group has taken credit for the attacks.
Hamas leadership in Gaza alleges that radical "jihadi" Islamist movements are to blame for the bombings, A-Sharq Al-Awsat reports.
Ja’abri also told Hamas leadership in his dispatch that he believes Hamas had made several serious errors in ruling the Gaza Strip.
Hamas seized control of the region in the summer 2007 following a bloody confrontation with rival Palestinian movement, the secular Fatah party.
