BEIRUT – A convoy of Islamic State fighters began a new attempt to reach territory held by the militant group in eastern Syria on Thursday after being blocked by U.S.-led airstrikes, despite warnings of more military action.
More than 300 lightly armed IS fighters and about 300 family members are being evacuated from Syria’s western border with Lebanon under a cease-fire agreement involving the ultra-hardline group, the Syrian army and the Lebanese Shiite group Hezbollah.
But the U.S.-led coalition fighting IS in Syria opposes experienced combatants being transferred to a battle zone in which it is active, and used warplanes on Wednesday to halt the convoy by damaging the road ahead. Coalition jets also struck fighters on their way to meet the convoy.
A commander in the pro-Syrian government military alliance said the convoy had headed north toward the town of Sukhna on Thursday after being halted in the desert and would try to reach Deir al-Zor province, close to the border with Iraq.
The coalition made clear it might strike IS fighters again if they were separated from civilians.
“We will continue to monitor the convoys in real time … and take advantage of known ISIS (fighters) in open areas away from civilians and strike them,” the coalition spokesman, Col. Ryan Dillon, said by telephone on Thursday.
Dillon said on Wednesday the coalition was “not bound by these agreements,” referring to the cease-fire deal and making clear it was being used to move fighters from one location to another “to fight yet again.
But the standoff shows the tangled nature of a war theater divided into several overlapping conflicts, and where the engagement of local, regional and global powers is further complicated by a mosaic of alliances and enmities.
Six years into Syria’s civil war, in which Islamic State has seized swaths of land, the jihadi group is on the retreat across the region, losing ground to an array of foes.
In Syria, the government of President Bashar Assad has rapidly gained ground this year as the army advanced eastward, backed by Russia and allied Iran-backed militia including Hezbollah, toward its besieged enclave in Deir al-Zor.
But in the north, the United States — which opposes Assad, Iran and Hezbollah — has led a coalition backing Kurdish and Arab militias as they assault Islamic State’s former Syrian capital of Raqqa.
Hezbollah-affiliated media have reported that the Syrian town of Al-Bukamal, close to the border with Iraq, is the final destination for the convoy.
Hezbollah has been one of Assad’s closest allies in the war and it trumpeted the departure of Islamic State, after that of two other militant groups, from the Lebanon border as a “day of liberation.
Iraqi Prime Minister, Haider al-Abadi said on Thursday it was “unacceptable” to ferry more jihadi fighters from another battlefront in Syria to the edge of Iraqi territory, prompting a statement from Hezbollah defending the move.
Iraq has formed a dedicated intelligence operations room to monitor and track the jihadis, a senior Interior Ministry official told state media, saying the convoy included “elite commanders” of Islamic State.
After it was blocked from moving eastward on Wednesday, the convoy headed north within government territory to try to move into Islamic State land from a new location.
The commander in the pro-Assad military alliance said the convoy would head on again after an exchange of dead combatants and prisoners. The bodies of an Iranian killed in the fighting and two other dead fighters were to be swapped for 25 wounded IS fighters traveling with the convoy, the commander said.
In Tehran, the country’s Revolutionary Guards said on their website that the dead Iranian, whom they identified as Mohsen Hojaji, would be returned at an unspecified date for a funeral and burial. The fighters retained light weapons but left heavier arms in their enclave after being evacuated from western Lebanon following heavy fighting there.
Such deals have increasingly been used by the Syrian army and its allies to press besieged rebels to surrender their enclaves and to relocate to insurgent-held territory elsewhere, but this is the first such deal involving Islamic State.
In the process, Islamic State revealed the fate of nine Lebanese soldiers it took captive in its border enclave in 2014, as well as surrendering a Hezbollah prisoner.
An official in the Syrian Arab Red Crescent, which is helping with the exchange, has entered Islamic State territory to accompany the prisoner back to the government-held area, the commander in the pro-Assad military alliance said.
Hezbollah-aligned al Akhbar newspaper in Lebanon reported on Thursday that some IS leaders in eastern Syria did not want members of the group who had surrendered territory to be welcomed back into their self-declared caliphate.
