DUBAI, United Arab Emirates – The United Arab Emirates launched airstrikes today against the Islamic State group from an air base in Jordan, marking its return to combat operations against the militants after halting the strikes late last year.

The Gulf federation’s official WAM news agency quoted the General Command of the UAE Armed Forces as saying that Emirati F-16s carried out a series of strikes this morning.

The fighters returned safely back to base after striking their targets, the statement said. It did not elaborate, nor did it say whether the strikes happened in Syria or Iraq. The militants hold roughly a third of each country in a self-declared caliphate.

The Emirates is one of the most prominent Arab members of the U.S.-led coalition against the Islamic State group.

American officials say the Emirates halted airstrikes in December after a Jordanian pilot, Lt. Muath al-Kaseasbeh, was captured when his plane crashed behind enemy lines. Al-Kaseasbeh was later burned alive by the militants.

The Emirates had not commented on the suspension, and today’s statement was the first confirmation it had restarted combat operations.

It has continued to provide logistical support to the campaign by hosting coalition warplanes at its air bases on the southern rim of the Persian Gulf.

American defense officials last week said they moved search-and-rescue aircraft closer to the battlefield, helping ease allies’ concerns about the coalition’s ability to aid downed aircrews.

The announcement came as Syria’s President Bashar Assad said in comments published today that his government has been receiving general messages from the American military about airstrikes targeting the Islamic State group inside Syria but that there is no direct cooperation.

In an interview with the BBC, Assad said the messages are conveyed through third parties, such as Iraq.

“Sometimes they convey message, general message, but there’s nothing tactical,” he said.

A U.S.-led coalition that includes four Arab countries is conducting airstrikes in Syria as part of an international campaign against Islamic State extremists. They share the skies with Assad’s air force, which also targets the militants.

Syrian officials have maintained that they have not been consulted about the airstrikes since they started in September – only informed through third parties in the beginning.

In the interview, Assad also denied his forces have used barrel bombs. The government’s use of the crude explosive devices, usually dropped by helicopters, has been widely documented by international human rights organizations and residents of opposition-held areas in Syria. The barrel bombs, which cannot be precisely targeted, have killed thousands of civilians, according to Syrian activists.

“I know about the army, they use bullets, missiles, and bombs. I haven’t heard of the army using barrels, or maybe, cooking pots,” Assad said, apparently making light of the allegations.

Pressed again about their use, he replied: “They’re called bombs…. There is no barrel bombs, we don’t have barrels.”
