The only crossing between Syria and Turkey that is approved by the United Nations for transporting international aid into Syria has been unusable since the earthquake struck, according to aid groups in the region, complicating an already fraught process.
The crossing, known as Bab al-Hawa, has been the lone link for aid for the past nine years.
Turkey is a member of the North Atlantic Treaty Organization and maintains friendly diplomatic relations with much of the world, giving it access to support and direct aid.
But Syria, under sanctions because of President Bashar al-Assad’s regime and the country’s civil war, cannot receive direct aid from many countries. Nongovernmental organizations must deliver the aid, making the crossing from Turkey a lifeline.
“If Bab al-Hawa is not functioning, technically speaking, there wouldn’t seem to be any other way to get cross-border aid into northwestern Syria,” said Julien Barnes-Dacey, the director of the Middle East program at the European Council on Foreign Relations, referring to the region affected by the earthquake.
“Even getting to Bab al-Hawa seems to be a huge ordeal at the moment,” he added. “It’s not as if the roads are functioning into Syria from Turkey.”
In recent years at the United Nations, Russia, a supporter of Mr. Assad, has tried to block aid from Turkey to opposition areas of Syria and instead have it all distributed from the capital, Damascus, which is controlled by the government.
Speaking at the United Nations on Monday, Bassam al-Sabbagh, the Syrian representative, called for sanctions to be removed, saying they were obstructing aid, and suggesting that aid should come through the government in Damascus instead.
“We are determined to do what we can to address the humanitarian needs of the Syrian people,” Ned Price, the State Department spokesman, said in a briefing on Monday. “We’ve done that over the course of the 12-year civil war to the tune of billions of dollars. We do that through a different process,” he added, referring to the nongovernmental groups that access Syria through Turkey.
The border appeared to be closed for logistical reasons, including that workers on both sides had been affected by the quake, said Sharvan Ibesh, the executive director of the Bahar Organization, an aid group based in the Turkish city of Gaziantep, where the earthquake struck. “There is nothing clear with regards to the crossings,” he said.
Aid organizations face other logistical issues in the aftermath of the earthquake.
“Antakya airport and the road from Antakya to Bab al-Hawa are trashed, as is the road from Gaziantep to Antakya,” Emma Beals, an adviser at the European Institute of Peace, wrote on Twitter, referring to an airport in southern Turkey.
The destruction in Turkey is likely to affect the rescue efforts in Syria.
“What is particularly bad with the current situation is that normally when a crisis happens in Syria, the situation on the Turkish side is fine,” said Mr. Ibesh, of the Bahar Organization aid group. “But the Turkish provinces along the Syrian border are themselves afflicted as well.”
