BAGHDAD — Tens of thousands of Syrian Kurds swarmed across a bridge into neighboring Iraq's northern self-ruled Kurdish region over the past few days in one of the biggest waves of refugees since the rebellion against President Bashar Assad began, U.N. officials said Monday.
The sudden exodus of around 30,000 Syrians amid the summer heat has created desperate conditions and left aid agencies and the regional government struggling to accommodate them, illustrating the huge strain the 2½-year-old Syrian conflict has put on neighboring countries.
The mostly Kurdish men, women and children who made the trek join some 1.9 million Syrians who already have found refuge abroad from Syria's relentless carnage.
"This is an unprecedented influx of refugees, and the main concern is that so many of them are stuck out in the open at the border or in emergency reception areas with limited, if any, access to basic services," said Alan Paul, emergency team leader for the Britain-based charity Save the Children.
"The refugee response in Iraq is already thinly stretched, and close to half of the refugees are children who have experienced things no child should," he said, adding that thousands of refugees were stranded at the border, waiting to be registered.
The U.N. said the reason for this flow, which began five days ago and continued unabated Monday, is unclear. But Kurdish areas in northeastern Syria have been engulfed by fighting in recent months between Kurdish militias and Islamic extremist rebel factions with links to al-Qaida. Dozens have been killed.
Following the assassination of a prominent Kurdish leader late last month, a powerful Kurdish militia said it was mobilizing to expel Islamic extremists.
On Monday, activists said fighters from al-Qaida-linked jihadi groups shelled areas in the predominantly Kurdish town of Ras al-Ayn with mortars and artillery, coinciding with clashes in the area between Kurdish gunmen and jihadi fighters.
"Syrian refugees are still pouring into Iraq's northern Kurdish region in huge numbers, and most of them are women and children," said Youssef Mahmoud, a spokesman for the U.N. refugee agency in Iraq's Kurdish region.
"Today, some 3,000 Syrian refugees crossed the borders, and that has brought the number to around 30,000 refugees since Thursday."
The latest wave has brought the overall number of Syrian refugees in the Kurdish region to around 195,000, he added.
The U.N. High Commissioner for Refugees has set up an emergency transit camp in Irbil, the capital of Iraq's Kurdish autonomous region, to house some of the new arrivals. Some of the refugees were said to be staying in mosques or with family or friends who live in the area, according to the agency.
At one camp near Irbil, dozens of refugees carrying their bags, belongings and babies roamed through rows of tents, footage shot by AP Television News showed. Some men lined up to get blocks of ice from a pickup truck. Children huddled around a truck to get watermelon distributed by regional security forces.
UNHCR said it is sending 15 truckloads of supplies — 3,100 tents, two pre-fabricated warehouses and thousands of jerry cans to carry water — from its regional stockpile in Jordan. It said the shipment should arrive by the end of the week.
Kurds are Syria's largest ethnic minority, making up more than 10 percent of the country's 23 million people. They are centered in the poor northeastern regions of Hassakeh and Qamishli, wedged between the borders of Turkey and Iraq. There are also several predominantly Kurdish neighborhoods in the capital, Damascus, and Syria's largest city, Aleppo.
Bahzad Ali Adam, deputy governor of Iraq's Dahuk province, which borders Syria, said the latest flow will put more strain on the budget and public services in the region, which is also home to thousands of mainly Iraqi Arabs and Christians who have fled the violence in other parts of the country.
"The refugees need place to live, food and health services," Adam, who heads the operation room to receive Syrian refugees, said in a phone interview from Baghdad.
Earlier this month, the president of Iraq's autonomous Kurdish region, Massoud Barzani, vowed to defend Syria's Kurds. He gave no details on how he would do so, but Iraqi Kurdistan boasts a powerful and experienced armed force known as the peshmerga.
Armed intervention by Iraqi Kurds would carry enormous risks and appears unlikely. Still, the pledge, along with the fighting, shows the potential of Syria's conflict to spread to neighboring countries and become a full-blown regional war.
The Kurdish exodus is just one layer in Syria's increasingly complex civil war, which has killed more than 100,000 people, ripped apart the country's delicate sectarian fabric and destroyed cities and towns. Assad's regime has used warplanes, tanks and ballistic missiles to try to pound rebellious areas into submission.
The rebels, along with the U.S. and other Western powers, say the Assad regime has also used chemical weapons in the conflict. The Syrian government and its ally, Russia, blame the opposition for the alleged chemical attacks.
On Monday, a team of U.N. experts began their long-awaited investigation into the purported used of chemical arms.
The team's task is to determine whether chemical weapons have been used, and if so, which ones. Its mandate does not extend to establishing who was responsible for an attack, and that has led some observers to question the overall value of the probe.
In Monday's violence, the Britain-based Syrian Observatory for Human Rights said regime forces in the coastal province of Latakia recaptured nine villages as well as all of the hilltop military observation posts that rebels seized two weeks ago.
