LONDON: Syrian authorities have reported that four security personnel died and two were injured during an attack on a government checkpoint in the city of Raqqa — located in the northeast of the country — on Monday.

The Internal Security Forces said that one of the attackers had been neutralized, and that security units were currently conducting a thorough sweep of the surrounding area to identify and eliminate the remaining members of the cell responsible for the attack, according to the Syrian Arab News Agency.

It marks the second violent attack in the region within 48 hours targeting the Internal Security Forces. The same checkpoint was attacked on Sunday, resulting in another operative being neutralized, as reported by SANA.

Raqqa was under Daesh control from 2014 to 2017. It was regarded as the group’s capital.

Government forces of the Syrian Arab Republic regained control of the region in January following a ceasefire and integration agreement with the Kurdish-led Syrian Democratic Forces.
