Turkish troops and their Syrian rebel allies attacked Kurdish militia in northeast Syria on Wednesday, pounding them with air strikes and artillery before starting a cross-border ground operation that could transform an eight-year-old war.
The assault began days after U.S. President Donald Trump pulled American troops out of the way, prompting denunciations from senior members of his own Republican Party who say he abandoned the Syrian Kurds, loyal allies of Washington.
“The Turkish Armed Forces and the Syrian National Army have launched the land operation into the east of the Euphrates river as part of the Operation Peace Spring,” the Turkish defense ministry tweeted after nightfall, following a day of pounding the area from the air.
Turkish media reported troops entering Syria at four points, two of them close to the Syrian town of Tel Abyad and two close to Ras al Ain further east.
Turkey told the United Nations Security Council in a letter seen by Reuters that its military operation would be “proportionate, measured and responsible.” The 15-member body will meet on Thursday to discuss Syria at the request of the five European members, Britain, France, Germany, Belgium and Poland.
Thousands of people fled Ras al Ain toward Hasaka province, held by the Kurdish-led Syrian Democratic Forces (SDF). The Turkish air strikes killed at least five civilians and three fighters from the SDF and wounded dozens of civilians, the SDF said.
Reuters journalists at Akcakale on the Turkish side of the frontier watched as explosions struck Tel Abyad. After dark, the red flare of rockets could be seen fired across the border into Tel Abyad, and flames burned near the town. Explosions from Tel Abyad could be heard eight hours into the bombardment. A witness reached by telephone said civilians were fleeing en masse.
SDF fighters repelled a ground attack by Turkish troops in Tel Abyad, SDF spokesman Mustafa Bali said on Twitter.
The assault on the Kurds – for years Washington’s main allies on the ground in Syria – is potentially one of the biggest shifts in years in the Syrian war that has drawn in global and regional powers. The Kurds played a leading role in capturing territory from Islamic State, and now hold the largest swathe of Syria outside of the hands of President Bashar al-Assad.
Russia, Assad’s strongest foreign ally, urged dialogue between Damascus and Syria’s Kurds.
Trump’s decision to pull forces out of the way was denounced by some Kurds as a “stab in the back”.
Trump called the Turkish assault a “bad idea” and said he did not endorse it. He expected Turkey to protect civilians and religious minorities and prevent a humanitarian crisis, he said.
Turkish President Tayyip Erdogan, announcing the start of the action, said the aim was to eliminate what he called a “terror corridor” on Turkey’s southern border.
European and Arab countries called on Ankara to halt.
Turkey had been poised to enter northeast Syria since the U.S. troops who had been fighting alongside Kurdish-led forces against Islamic State started to leave.
A Turkish security source told Reuters the military offensive, dubbed “Operation Peace Spring”, opened with air strikes. Turkish howitzer fire then hit bases and ammunition depots of the Kurdish YPG militia. Turkey says the YPG, the main component of the U.S.-backed SDF, is a terrorist group linked to Kurdish insurgents that have fought in Turkey for years.
The artillery strikes, which also targeted YPG gun and sniper positions, were aimed at sites far from residential areas, the Turkish source said.
The Turkish army has hit a total of 181 militant targets with air strikes and howitzers since the start of the operation, the defense ministry said on Wednesday.
Explosions also rocked the Syrian border town of Ras al Ain, according to a reporter for CNN Turk. The sound of warplanes could be heard above and smoke rose from buildings in the town, the CNN reporter said.
Turkish media said several mortar shells had landed on the Turkish side of the border but there were no casualties.
