BEIRUT – Syrian rebels said Friday they would retaliate for what they described as the assassination of one of their senior commanders by an al-Qaida-affiliated group, threatening to widen a rift between moderate and jihadist opposition forces fighting to topple President Bashar Assad.
The killing of Kamal Hamami, a member of the Western-backed Free Syrian Army’s top executive body, comes amid heightened tensions on the opposition side as jihadist groups extend their influence in rebel-held areas of northern Syria.
Rebels said that Hamami, whose nom de guerre is Abu Bassir al-Ladkani, was shot dead Thursday in the coastal province of Latakia by gunmen from the Islamic State of Iraq and the Levant.
With the rebel forces struggling to fend off Assad’s troops in the central city of Homs, infighting among their disparate factions could play to the government’s advantage. Jihadist groups such as the Islamic State of Iraq and the Levant — an offshoot of the main Islamist opposition group in Syria, Jabhat al-Nusra — are fewer in number than more moderate forces, but they are considered some of the best-equipped and most effective fighters on the battlefield.
Moderate rebels say they have been left behind militarily as radical Islamist groups receive arms and financial support from elsewhere, while weapons pledged to the moderates by the United States have yet to reach them.
Although al-Nusra is seen as “more adept at coordinating its efforts on the battlefield with other groups,” a U.S. official in Washington said, “whether the groups will be able to set their differences aside and cooperate against Assad is really an open question.” The official spoke on condition of anonymity to comment on a still-fluid situation.
“The Islamic State phoned me saying that they killed Abu Bassir and that they will kill all of the Supreme Military Council,” a spokesman for the FSA, Qassem Saadeddine, said, referring to the body’s executive.
“We are going to wipe the floor with them,” a rebel commander who spoke on condition of anonymity told Reuters news agency.
The details of Thursday’s killing were unclear, but the Britain-based Syrian Observatory for Human Rights said that Hamami, one of 30 military leaders on the Supreme Military Council, was shot after an attack on one of the checkpoints he had set up in a mountainous area outside the city of Latakia. Saadeddine said he had been discussing battle plans with members of the Islamic State of Iraq and the Levant.
Despite growing frictions, moderate factions and jihadist groups do still coordinate on the ground, said Charles Lister, an analyst at IHS Jane’s Terrorism and Insurgency Center. He said that is unlikely to change, although the FSA may use the assassination for political gain.
“Moderate forces could use this as a way to prove to the West that they are willing to break relations with jihadis in order to get more Western assistance,” he said. “The reality is very different for the commanders on the ground.”
Louay al-Mokdad, a political and media coordinator for the FSA, said that Hamami was killed by “the forces of evil.”
“We must take the necessary measures, on all levels, and the Islamic State of Iraq and the Levant brigades should hand over to us those who killed Hamami,” he told Al-Arabiya television. FSA officials were to hold an emergency meeting Friday to discuss their response, he said.
Mouaz al-Khatib, a moderate Syrian cleric and former head of the Syrian Opposition Coalition, said in a statement that the killing by “a criminal gang that knows no religion . . . and believes jihad to be blood and murder” could be the beginning of a division that could devastate the country.
The stamp of the Islamic State of Iraq and the Levant has appeared on graphic video footage from Syria showing beheadings. The group had not released an official comment on the assassination by Friday night. However, a Twitter feed often used to disseminate the group’s views acknowledged the killing, saying: “This man was blaspheming God . . . so God’s ruling was implemented against him.”
