Sri Lankan authorities have increased the remand on two Maldivians by seven days.

Adam Manik and Hassan Manik’s initial 10-day remand expired on Friday.

They were arrested during Sri Lanka’s ongoing search operation that began after the Easter attacks. During the operation, Sri Lankan authorities arrested 20 Maldivians and re-arrested some after releasing them. Five Maldivians are currently in remand.

After declaring a state of emergency, Sri Lankan authorities have also established check posts in various parts of the country.

The Maldives ambassador has said that the Sri Lankan government has notified them that a large number of Maldivians have been found with expired visas, and so urged every Maldivian resident to check their documents and renew them if necessary.

With more than 20,000 Maldivian residents, Sri Lanka has the largest Maldivian community outside of the native country.

The Sri Lankan terror attacks on April 21 killed more than 250 people and injured more than 500.
