Hamas said it is willing to "fully cooperate" with Lebanese authorities in the investigations into the bomb blast late last month which killed two Hamas members, local newspaper Daily Star reported Friday.
Hamas representative in Lebanon Osama Hamdan Thursday said the group will help discover who was behind the December explosion in the southern suburbs of Beirut, according to the report.
He also denied that Hamas carried out military activities in the country, Xinhua reported.
Also on Thursday, Lebanese Military Investigative Magistrate Rahef Ramadan interrogated at the Military Hospital an arrested and wounded Hamas member, who was present when the explosion took place.
On Dec. 26, a car bomb explosion in Beirut's southern suburb Dahiyeh killed three people, including two Hamas members.
The Palestinian Islamist group said the blast was targeted them, but they did not accuse any group of the attack. The incident is still under investigation.
