Turkish officials have expressed frustration with the USA for leading a coalition to set up a new force of 30,000 personnel along the Syrian's northern border, Reuters reported Sunday.
"In coming days, we will continue our operations in Afrin to clear our southern border" of terrorists, Erdogan told a meeting of his party in Tokat province on Sunday.
Afrin is controlled by a Kurdish militia known as the YPG, which Turkey views as a terror group and an extension of the Kurdish insurgency raging in its southeast.
Late previous year, Turkish troops were then deployed to rebel-held northern Idlib province, south of Afrin, as part of an agreement with Iran and Russian Federation to implement four so-called de-escalation zones in flashpoint areas around Syria.
"More Kurds will serve in the areas in northern Syria". "It's absolutely not possible to accept this", Kalin said, and he repeated that Turkey would defend itself.
A YPG spokesman in Afrin told The Associated Press news agency fighting broke out after midnight between his unit and Turkish troops near the border.
"In case the terrorists will not surrender, we will destroy them", he added. "We know this. This is not what allies do", Erdogan said.More news: American Red Cross assisting 19 families displaced by fires in Newark

YPG will fight to "defend our gains, our territories", Roj said.
She called Turkey's operation against Afrin a "violation" that "undermines worldwide efforts to reach a political solution in Syria".
PKK is blacklisted as a terrorist organisation by Turkey and its Western allies.
The source, who spoke on condition of anonymity due to restrictions on talking to the media, said that the vehicles and supplies had been sent as reinforcements to the Turkish border units.
Turkey has been working closely with Russian Federation and Iran to end the almost seven-year Syrian war, despite Moscow and Tehran supporting Syrian President Bashar al-Assad - and Ankara backing the anti-Assad opposition.
The Turkey-PKK conflict has killed an estimated 40,000 people since 1984, including more than 3,300 state security forces, militants and civilians since the resumption of hostilities in July 2015.
