At least 30 Syrian troops were killed in Turkish counter-fire in Syria's northwestern province of Idlib, Turkish President Tayyip Erdogan said here on Monday.
"We have responded in kind to these attacks and will continue to do so... We are determined to continue our operations for the security of our country, people and our brothers in Idlib," he told reporters.
Erdogan said Turkey will continue to retaliate against attacks on its forces in Idlib.
The Syrian Observatory for Human Rights, a war monitor, reported that about six Syrian government troops were killed by Turkish shelling.
The retaliation came after four Turkish soldiers were killed and nine others wounded by Syrian shelling in Idlib, said the Turkish Defense Ministry.
