BEIRUT — The Islamic State group has killed 12 people it held captive in Syria’s ancient Palmyra by shooting and beheading them, with some of the slayings carried out in the city’s second-century Roman amphitheatre, activists said on Thursday. The extremist group had recaptured the city in December from government troops — nine months after Islamic State was expelled from there in a Russia-backed offensive and while Syrian government forces were focused on retaking the eastern half of the city of Aleppo from rebels. When they previously controlled Palmyra, Islamic State militants had used the Roman amphitheater for public killings, including those in a video showing 25 boys with pistols shooting captured Syrian soldiers, the ancient colonnades visible in the background.

BEIRUT, Jan 19 (Reuters) - Islamic State militants put at least 12 people to death in execution-style killings in the ancient city of Palmyra, which they re-captured from the government for a second time in December, the Syrian Observatory for Human Rights reported on Thursday. They were captured as they tried to escape the Islamic State offensive on Palmyra last month. The Britain-based Syrian Observatory for Human Rights says four of the victims, teachers and government employees, were beheaded. The activists say the killings took place on Wednesday

Some of the killings were carried out in the 2nd century Roman amphitheater, while others were said to have taken place in the courtyard of the Palmyra museum or in a former Russian base in Palmyra.
