In February this year, Mr Zakka announced an indefinite hunger strike, demanding Lebanon’s newly formed cabinet include a commitment to hostages in its policy statement. As a permanent US citizen, Mr Zakka’s imprisonment became a political issue in the United States too, although it is not clear what role, if any, America played in his release. According to a website dedicated to the cause of Zakka's freedom, he is a prominent IT expert who specialises in Arab information and communications. He has worked for Cisco, Microsoft and contractually for the USAID, according to the Free Nizar Zakka website. Mr Ibrahim is garnering a reputation as an effective force in Lebanese politics, and has been tasked with undertaking a string of difficult negotiations, including with militant groups and Al Qaeda affiliates. He built contacts and praise as a savvy negotiator during his time as head of security for south Lebanon that involved building the trust of numerous armed groups that operate in the Palestinian refugee camps, and he brokered several ceasefires after rounds of fighting. Perhaps his most high-profile deal came in 2017 when he managed to get ISIS militants on the Lebanese border to give up the locations of bodies of Lebanese soldiers kidnapped when they overran the north-eastern town of Arsal three years previously. The remains of eight soldiers were recovered from the mountainous border area between Syria and Lebanon, bringing closure to the families who had been holding a years-long sit-in outside the prime minister’s office demanding the government locate find the remains of their sons. While it remains unclear if Gen Ibrahim’s discovery of the bodies was tied to the larger deal to end a Hezbollah offensive against the ISIS militants who had held the soldiers, shortly after they were returned to Beirut the fighters were allowed to leave by bus for Syria’s Deir Ezzor.
