because according to Palestinian news there is little question that it was an assassination and the blame seems placed on Assad's forces for good reason, Hamas supports the Syrian rebels, and not on Mossad as some unnamed Hamas spokesman supposedly said
The Supreme Council of the Syrian Revolution said in a statement that Ghanaja's body was found in his home in Damascus' Al-Yarmouk refugee camp with clear signs of torture, including cigarette burns. Ghanaja's belongings -- including his laptop, weapons and money -- were not stolen, the council said.
The Beirut-based satellite channel Al-Mayadeen reported that Hamas was waiting for a forensic report before responding to the assassination.
In a statement in Gaza, Hamas did not immediately accuse Israel of involvement in Ghanaja's death, saying only that it had launched an investigation "to identify the party behind the deplorable crime".
Several websites affiliated to the opposition to President Bashar Assad blamed the Syrian regime for Ghanaja's killing and said Assad's forces murdered the Hamas leader as a message to the movement not to reject its long-time ally.

Leaders of the Palestinian Islamist movement Hamas turned publicly against their long-time ally President Bashar al-Assad of Syria on Friday, endorsing the revolt aimed at overthrowing his dynastic rule.
The policy shift deprives Assad of one of his few remaining Sunni Muslim supporters in the Arab world and deepens his international isolation. It was announced in Hamas speeches at Friday prayers in Cairo and a rally in the Gaza Strip.
Hamas went public after nearly a year of equivocating as Assad's army, largely led by fellow members of the president's Alawite sect, has crushed mainly Sunni protesters and rebels.
