Sri Lanka's president on Sunday banned burqas, the garment worn by some Muslim women, calling them "a security risk and a flag of fundamentalism," CNN reports.
The move follows a series of bombings on Easter Sunday that killed more than 250 people and wounded at least 500 in Sri Lankan churches and hotels.
The Islamic State (ISIS) jihadist group later claimed responsibility for the attacks.
"President Maithripala Sirisena took this decision to further support the ongoing security and help the armed forces to easily identify the identity of any wanted perpetrators," according to a press release from the president's office.
The ban goes into effect Monday.
Sri Lanka remains on high alert a week after the bomb attacks, with warnings that more violence could be imminent.
Police have carried out a number of raids in the eastern part of the country in their search for the attackers.
A ban on Muslim face veils has been approved in recent years in several European countries.
France outlawed the wearing of a niqab (full face veil) - part of the burqa, or full body covering worn by Muslim women - in public in April 2011.
An Austrian law that forbids any kind of full-face covering, including Islamic veils, came into force in later 2017, while a ban in Denmark on the Islamic full-face veil in public spaces came into force last year.
