Kurdish authorities in northeast Syria warned Tuesday that a UN vote to scrap a key entry point for cross-border aid will lead to medical shortages and expose them to regime control. "There will be no (UN) aid entering the region except from government-held areas, which will give the regime a greater ability to control aid distribution," said Abdel Kader Mouwahad, director of humanitarian affairs for Kurdish authorities, according to AFP. The Yaroubiya crossing along the Iraqi border, was a key entry point for UN-funded medical aid reaching a Kurdish-held region where an estimated 1,650,000 people are reliant on humanitarian assistance, according to aid groups. The UN had used it to deliver medical supplies that the Syrian regime had not permitted via Damascus. But it was scrapped last Friday after the UN Security Council voted to scale back cross-border aid deliveries to Syria, under pressure from regime ally Russia. This leaves Syrias Kurds with the unofficial Samalka crossing with Iraqi Kurdistan, which is not used for UN aid. Yaroubiyas closure will cripple at least half of the healthcare response in an area ravaged by battles against the ISIS group as well as a Turkish offensive in October that displaced 200,000 people. It will disrupt "60 to 70 percent of medical assistance to Al-Hol", an overcrowded desert camp brimming with tens of thousands of civilians and ISIS families, said Mouwahad. It will also threaten the delivery of UN-funded medicine and medical equipment to a key hospital in the city of Hassakeh as well as critical medical points established around two towns near the Turkish border hard hit by Turkeys latest incursion, he told AFP. He said that UN support for the Kurdish Red Crescent may also be slashed.Pressure card Aggravating the situation, UN-funded aid to northeast Syria must now come either from Turkey or from regime-held areas with permission from Damascus, which aims to reintegrate Kurdish-held areas into the states fold. But Mouwahad said it was "impossible" for aid to enter from Turkey, which views Kurdish forces in Syria as a "terrorist" offshoot of the Kurdistan Workers Party (PKK) on its own soil. Damascus, for its part, will use aid supply lines as a "pressure card" to encourage Kurds to relinquish the semi-autonomy they have achieved during Syrias nine-year-old conflict. "The aim is to politically intimidate the Kurdish administration," he said. Syrian troops have already deployed in much of the northeast in recent months as part of deal with the Kurds who are seeking protection from Turkey. Damascus has also called on the Kurdish-led Syrian Democratic Forces who have fought ISIS to integrate into its military, a proposal the Kurds rejected. Redur Khalil, a senior SDF official, said the latest UN move was a "dangerous development". "Aid will be barred from reaching the region" under the restrictions on entry points, he said on Twitter, urging the United Nations to intervene. International Crisis Group analyst Sam Heller said the curb on aid entry points "further concentrates power in Damascus, and in Syrian regime hands". "Its another instance of Damascus benefiting from its control of the Syrian states institutions and international legitimacy... to enforce dependence," he said.
