Turkish President Recep Tayyip Erdogan vowed to “destroy all terror nests” in Syria today, as he kept up his verbal attacks against the United States over its continuing support for the Syrian Kurdish People’s Protection Units (YPG).

Speaking before members of his ruling Justice and Development Party, Erdogan asserted, “In a short span of time, we will destroy all terror nests, one by one, in Syria, starting from Afrin and Manbij.”

The volley of threats followed a night of shelling by Turkish forces and their Free Syrian Army allies targeting Afrin, the Kurdish-majority enclave on the Turkish border that is under YPG control.

A local resident contacted via WhatsApp told Al-Monitor on condition that they not be identified that shells began landing at 8 p.m. Syrian local time and continued unabated till 3 a.m. Some, the resident claimed, fell within close proximity of a nearby Russian military camp. “The noise was infernal and civilians are terrified,” said the resident, who lives 8 kilometers (5 miles) south of the Turkish border. “But nobody was killed and save for a few shattered windows there was hardly any damage.”
