BEIRUT (AP) ― Islamic State fighters captured a major military air base in northeastern Syria on Sunday, eliminating the last government-held outpost in a province otherwise dominated by the jihadi group, activists and state media said.
Tabqa airfield ― home to several warplane squadrons, helicopters, tanks, artillery and ammunition bunkers ― is the third military base in the area to fall to the extremists since last month. Those victories are part of the Islamic State group’s aggressive push to consolidate its hold on northern and eastern provinces, while also expanding the boundaries of its self-styled caliphate straddling the Syria-Iraq border.
The jihadis launched their long-anticipated offensive last week to seize the sprawling Tabqa facility, located some 45 kilometers from the extremists’ stronghold in the city of Raqqa along the Euphrates River.
After several failed efforts to breach the walls in recent days, Islamic State fighters managed to punch through and storm the air base Sunday, the Britain-based Syrian Observatory for Human Rights said. Government warplanes carried out waves of airstrikes to try to beat back the attack, but those ultimately proved unable to stem the assault.
“Some of the Syrian regime troops pulled out, and now the Islamic State is in full control of Tabqa,” said Observatory director Rami Abdurrahman. “This makes Raqqa province the first to fully fall out of government hands.”
Another activist group, the Local Coordination Committees, also said the extremist group was in control of Tabqa.
The SANA state news agency confirmed that the government had lost the air base, saying troops “are successfully reassembling after evacuating the airport.” It said that the military was still “striking terrorist groups, inflicting heavy losses on them.”
The government had made significant investments in both weapons and manpower to try to hold onto Tabqa, making its fall both a symbolic and a strategic blow.
Islamic State fighters had been closing in on the base for weeks. When the fight finally came, it was bloody.
The Observatory said that at least 100 Islamic State fighters were killed and another 300 wounded in the fighting, numbers that exclude casualties from the final assault. It said more than 170 government troops also were killed Sunday alone, and there were reports that another 150 may have been captured.
Tabqa is the latest in a string of bases to fall to the Islamic State group as it strengthens its hold over a vast swath of territory in northern and eastern Syria. Last month, the extremists overran the sprawling Division 17 military base in Raqqa, killing at least 85 soldiers.
Two weeks later, they seized the nearby Brigade 93 base after days of heavy fighting.
The group’s trademark brutality was on full display after those victories. They killed army commanders and pro-government militiamen, decapitating them before putting their bodies and heads on display. The Observatory reported similar acts following the fall of Tabqa on Sunday.
In the neighboring province of Deir el-Zour, Islamic State fighters also have overwhelmed outposts held by Syrian rebels, systematically picking off towns and villages one by one through force and intimidation.
Their slow and steady push in northern and eastern Syria, as well as their lightning advance across Iraq, has brought under their control a stretch of territory running from Syria’s northern border with Turkey as far as the outskirts of Baghdad in central Iraq. The group has declared a self-styled caliphate in those lands to be governed under its strict interpretation of Islamic law.
Early this month, the United States began launching airstrikes against the group in northern Iraq. Those operations mark the first American military involvement in the country since the last U.S. forces withdrew in 2011.
The U.S. Central Command said in a news release Sunday that those airstrikes continued over the weekend with one destroying an Islamic State Humvee near the Mosul Dam and another destroying an “armed vehicle” near Irbil.
The mainstream Syrian opposition, which is fighting President Bashar Assad as well as the Islamic State group, has called for similar air raids against the extremists in Syria. The Obama administration has so far refused, wary of getting dragged into a bloody and complex civil war that the U.N. says has killed more than 190,000 people.
With Tabqa now in hand, the Islamic State group could focus on the battlefront in neighboring Aleppo province. The extremists have already captured at least a dozen towns and villages there in recent weeks, crushing mainstream Syrian rebels and advancing toward the city of Aleppo.
Also Sunday, an American held hostage in Syria by an al-Qaida-linked group was released, a relative and the U.S. government said.
The U.S. identified the freed American as Peter Theo Curtis, and said he now was safe and outside of Syria. The United Nations said it helped with the handover to U.N. peacekeepers in a village in the Israeli-annexed Golan Heights and that Curtis was released to American authorities after a medical checkup.
The administration provided no details about the circumstances of his abduction or his release. It was not known what prompted Curtis’ release, which comes days after militants beheaded a U.S. journalist abducted while covering the Syrian conflict.
Meanwhile, the foreign ministers of Saudi Arabia, the United Arab Emirates, Egypt, Qatar and Jordan met in the Red Sea city of Jidda, the official Saudi news agency said without providing details.
But Egypt’s Foreign Ministry said ahead of the talks that the group would discuss the security threat posed by the Islamic State group and search for ways to bring about a needed political solution to the Syrian crisis.
