Hamas fears Israel has managed to infiltrate its Damascus-based leadership, a senior Gaza-based group member told The Jerusalem Post on Tuesday.
The unnamed official said last month's assassination of top Hamas operative Mahmoud al-Mabhouh in Dubai had prompted an investigation into how Israel was receiving information regarding the movements of the group's people.
"Only a few people in the Hamas leadership knew about Mabhouh’s secret activities and movements," noted the official.
Hamas is also looking into the possibility that Israel has infiltrated the Syrian security services, which are responsible for the safety of the terror groups that operate out of Damascus.
Israel has denied involvement in Mabhouh's killing, and pointed out that Hamas has many other enemies in the region.
