Two main suspects connected to the recent Sri Lanka terror attacks have been detained by police, according to a local news portal citing police.

Two brothers believed to be the main suspects behind the series of bombings that targeted several churches and luxury hotels have been arrested and handed over to the Criminal Investigation Department of the Sri Lankan Police, Ada Derana reported.

Last week’s terror attacks killed at least 253 people and injured hundreds more. Islamic State (IS, formerly ISIL/ISIS) has claimed responsibility for the bombings.

Nearly 10,000 soldiers are searching the country for suspects linked to the attack, with over 70 individuals detained so far.

Fifteen bodies, including six children, were found at the site of a shootout that broke out Friday night between military police and suspected militants.
