140,000 Syrians displaced in past 3 days due to ongoing offensive

More than140,000 Syrians have been displaced in the past three days alone by violence in the country's northwest, bringing the total of those uprooted in a Syrian government offensive against the last opposition stronghold to over 800,000, the United Nations said Thursday.

The UNsaid at least 60 per centof the more than 800,000 displaced since Dec. 1 are children. The humanitarian crisis in the already overcrowded opposition-held enclave is compounded by freezing weather and a lack of supplies.

The government offensive, backed by Russia, has intensified and expanded to include southern and eastern Idlib province as well as southern and western Aleppo, an area home to an estimated fourmillion people. Most have already been displaced from other parts of Syria because of the ongoing conflict.

The humanitarian situation for people in northwest Syria is "at the most critical points," the UNsaid, as the massive scale of human displacement over such a short period of time has increased needs exponentially.

David Swanson, UNregional spokesperson for the crisis in Syria, said more resources, including funding, are immediately needed to save lives and alleviate suffering. He predicted the 800,000 figure will rise in the coming days as the government offensive continues.

"This level of displacement couldn't come at a worse time as more and more people are squeezed into an increasingly smaller area of land with little more than the clothes on their back," he said, describing people fleeing in the middle of the night to avoid detection in temperatures below zero.

"The crisis is deepening by the minute, but the international community remains indifferent," Swanson said.

Government forces, with Russian support, have focused their offensive on areas along a strategic highway that runs through opposition territory and connects the country's south to the north. The M5 highway, now secured by Syrian troops, had been out of government control since 2012 and accessing it was part of a now failed 2018 ceasefire agreement. Calls for a ceasefire have failed to stop the violence.

On Thursday, government troops continued to advance through the Aleppo countryside to secure their hold on the highway. Most of the villages and towns that sit alongside the highway are now empty, while hundreds of thousands are squeezing into displacement camps, open fields and tents to move away from the front lines.

The UNsaid 550,000 of the displaced are living in Idlib towns and villages already packed with displaced people. Another 250,000 have moved to northern Aleppo in areas administered by Turkey and allied Syrian groups.

Turkey, a sponsor of the ceasefire and a backer of the opposition, has sent thousands of troops into the area to stall the advances, sparking rare direct confrontations with Syrian troops.

The Syrian war, now in its ninth year, has pulled in international players including the U.S., Russia and Turkey. Russia has supported the Syrian government troops while the U.S. has led an international coalition fighting ISIS militants.

Also on Thursday, the U.S. military acknowledged its troops fired on and killed a Syrian combatant when government supporters attacked an American convoy in northeastern Syria a day earlier.

The clash Wednesday was a rare direct confrontation between a Syrian pro-government group and U.S. troops deployed in the increasingly crowded terrain near the border with Iraq and Turkey.

A convoy of U.S. armoured vehicles drove into a government-controlled area and was attacked by pro-government supporters, including armed men who fired at the soldiers and pelted them with stones and Molotov cocktails.

Col. Myles Caggins, spokesperson for the U.S.-led coalition, said the person killed was a combatant. He said the U.S. soldiers had come under fire and responded in self-defence. Syrian government media maintained the person killed was a civilian.

The U.S. maintains hundreds of troops in the area. In recent weeks, and following a Turkish invasion of villages and towns along its borders, the area has been swarming with Russian, Syrian government and Turkish troops. They are deployed in part to maintain the peace but also in the latest tug over territorial control in Syria's conflict.

Caggins said the patrol was planned, and the route passed through a pro-government area. The convoy of U.S. armoured vehicles passed through a Syrian military checkpoint, but government militia were also present.

The U.S. maintains lines of communication with Russia, Damascus's ally, to avoid such confrontations.

Videos showed government supporters attacking the vehicles and two men firing small arms at the convoy, which was flying the U.S. flag. Some residents pelted the convoy with stones, while another dumped a bucket full of dirt on the back of one vehicle.

U.S. soldiers were seen standing in the middle of the melee, trying to disperse the crowd. One U.S. vehicle was stuck in the dirt, apparently having veered into a ditch, while another had a flat tire.

"Despite U.S. troops' repeated de-escalation efforts, local militia members attacked U.S. troops with small arms weapons from multiple firing positions," Caggins said. "Coalition forces always have the right to self-defence and fired back at armed aggressors, killing one adult male combatant."
