Ankara's notice came in a statement to the US ambassador to Turkey, David Satterfield, a senior administration official said. In signaling the intent to invade, Erdogan appeared to buck threats of “economic obliteration” made by President Donald Trump on Monday, including possible sanctions.

It was not immediately clear what assets Turkey would use in the attack, though US partners on the ground said on Wednesday that warplanes had begun to carry out strikes against civilian areas. Experts who spoke to Al-Monitor said the incursion would likely be limited and face stiff resistance from the Kurdish-dominated Syrian Democratic Forces (SDF), which have received backing from the Pentagon.

“I think they have no intention of going deeper than 30 [kilometers],” Aaron Stein, director of the Middle East program at the Philadelphia-based Foreign Policy Research Institute, said of Turkey’s military plans. “[The attack] will achieve rapid success only to be hit with an insurgency.”
