Turkish forces, together with the Free Syrian Army, will cross the Syrian border "shortly", President Tayyip Erdogan’s communications director said early on Wednesday, as a surprise withdrawal of U.S. troops made way for the Turkish incursion.
Turkey has been poised to advance into northeast Syria since the U.S. troops began vacating the area in an abrupt policy shift by U.S. President Donald Trump.
On Tuesday, Turkish officials told Reuters that the military had struck the Syrian-Iraqi border to prevent YPG terrorists using the route to reinforce the region, though details of the strikes were hazy.
President Erdogan's aide Fahrettin Altun said that terrorist from the YPG in Syria could either defect or Ankara would have to "stop them from disrupting" Turkey's struggle against Daesh terrorists.
"The Turkish military, together with the Free Syrian Army, will cross the Turkish-Syrian border shortly," Altun said in a tweet extracted from a column written by him which was published in the Washington Post.
"Turkey has no ambition in northeastern Syria except to neutralize a long-standing threat against Turkish citizens and to liberate the local population from the yoke of armed thugs," the column said.
Turkey has said it intends to create a "safe zone" in order to return millions of refugees to Syrian soil, but the scheme has alarmed some Western allies as much as the risks posed by the military operation itself.
For Turkey, which views YPG in northeast Syria as terrorists because of their ties to the Kurdistan Workers' Party waging an insurgency inside Turkey, an influx of Syrians would help it secure a buffer against its main security threat.
Erdogan will visit the United States on Nov. 13 at Trump's invitation, a White House spokesman said. On Monday, Erdogan said U.S. troops had started to withdraw after a phone call he had with Trump, adding that talks between Turkish and U.S. officials on the matter would continue.
"We have moved the U.S. forces in northern Syria out of the path of potential Turkish incursion to ensure their safety," U.S. Defense Department spokesman Jonathan Hoffman said in a statement.
Russia, Syrian President Bashar al-Assad's strongest foreign ally, said it was not told in advance by Washington or Turkey about any agreements to pull U.S. troops. Amid deepening humanitarian concerns, United Nations Secretary-General Antonio Guterres urged all parties in northeast Syria to exercise maximum restraint and protect civilians.
Signalling a further potential shift in the region's power balance, the YPG said they might start talks with the Syrian government and Russia to fill a security vacuum in the event of a full U.S. withdrawal. Trump denied he had abandoned the YPG. But he praised Turkey as a trade partner, in a softening of tone hours after threatening to "totally destroy" Turkey's economy if it acted "off limits" in Syria.
Near the Turkish border town of Akcakale, across from Syria's Tel Abyad, a Reuters witness saw howitzers placed behind earth embankments on Turkey's side of the border, pointed towards Syria.
Some 60 km (40 miles) to the west, multiple launch rocket systems mounted on two trucks were deployed behind earth embankments near Suruc, opposite the Syrian border town of Kobani. Artillery was also stationed in the area, and soldiers wandered around a nearby military camp.
