(Reuters) - Turkish artillery hit targets near Syria’s Tel Abyad border town for a second day on Thursday, killing several Syrian soldiers according to activists and security sources, after a mortar bomb fired from the area killed five Turkish civilians.

Turkey’s government said “aggressive action” against its territory by Syria’s military had become a serious threat to its national security and sought parliamentary approval for the deployment of Turkish troops beyond its borders.

“Turkey has no interest in a war with Syria. But Turkey is capable of protecting its borders and will retaliate when necessary,” İbrahim Kalın, a senior adviser to Prime Minister Tayyip Erdoğan, said on his Twitter account.
