IS launches new assault on besieged eastern city in Syria

BEIRUT — Islamic State militants launched their biggest assault in a year on government-held areas of the contested city of Deir el-Zour yesterday, attacking from several fronts and triggering intense fighting in the eastern region bordering Iraq, the Syrian government and opposition activists said.

Syrian state TV said three people were killed and nine were wounded in IS rocket attacks on several neighborhoods of the city.

Intense fighting broke out between Syrian troops and the extremist group's fighters both inside the city and around the vicinity of a nearby military airport controlled by government forces. The militants had launched their multi-pronged attack starting from the area of Baghaliyeh near the northwestern tip of the city. Deir el-Zour carries strategic significance for IS as it links the group's Iraq territory to its de facto capital of Raqqa in Syria.

Loud explosions that shook the city were reported. Activists said Syrian warplanes were taking part in the battles.

The Deir Ezzor 24 news network reported ongoing clashes since the morning near Deir el-Zour military airport and other fronts in the city and said Syrian warplanes targeted Baghaliyeh and Ayash areas and the vicinity of an army base known as Brigade 137 west of the city.

The extremist group, which controls most of Deir el-Zour province, has kept the provincial capital under siege since 2014. Government forces have withstood the encirclement thanks to air-dropped humanitarian assistance and weapons and ammunition flown into the airport. Remaining residents have reported malnourishment and starvation amid severe shortages of food, water and fuel.

IS has tried to capture the government-held neighborhoods of Deir el-Zour and the city's suburbs over the past months without much success.

The Syrian Observatory for Human Rights said yesterday's offensive was the most intense since mid-January 2016, when the group killed dozens of people, most of them pro-government militiamen, in wide-scale attacks on the city that saw the group make significant advances. Most of those casualties took place in Baghaliyeh and the killings — many people were shot dead or beheaded — were some of the worst carried out by the extremist group.

The Observatory said the group has recently brought in reinforcements, including large amounts of ammunition and fuel, in preparation for the battle. It said at least 32 people were killed in yesterday's fighting, including 12 soldiers and allied militiamen and 20 IS fighters.

The Islamic State group, which in 2014 seized large parts of Iraq and Syria and established a so-called Islamic "caliphate" straddling both sides of the border, is under intense pressure in both countries where it has lost significant territory in recent months.

Meanwhile in northern Syria, opposition activists reported a series of government airstrikes on Idlib province over the past 24 hours, including an attack that killed at least 11, mostly civilians, in Maaret Misrin.

In Damascus, a government offensive to uproot rebels in control of a valley nearby continued, further threatening a fragile cease-fire that appeared to be fraying.

The cease-fire brokered by Russia and Turkey, who support opposing sides in the Syrian civil war, went into effect on Dec. 30. It excludes extremist groups such as the Islamic State group.
