"We understand the causes for the Euphrates Shield operation led by the Turkish armed forces in Syria. The perpetrators of the horrible terror attacks in Turkey in the majority of cases came from Syria. However, there is one 'but.' In compliance with the norms of international law, such operations should be conducted with the authorization of the United Nation or with the consent of the country where the operation is being carried out. This requirement was not met, and we regret for that," Karlov said in his speech at the private Atilim University in the Turkish city of Golbasi.
On August 24, Turkish forces, backed by US-led coalition aircraft, began a military operation dubbed Euphrates Shield to clear the Syrian border town of Jarabulus and the surrounding area of Daesh terrorists.
