(CNN)Any face covering that "hinders the identification of individuals in a way that threatens national security" is now banned in Sri Lanka, according to a statement from the country's President.
Sri Lanka bans all face coverings for 'public protection' after bomb attacks
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.
"(President Maithripala Sirisena) has made this decision to strengthen national security as well as to not inconvenience any demographic group so as to create a peaceful and harmonious society in Sri Lanka," said the presidential statement, which was released Sunday.
The ban took effect Monday, and applies to anything covering the face, which could include burqas, niqabs and helmets or masks.
"All sorts of face covers that hinders the identification of individuals in a way that threatens national security shall be banned with effect from 29 April 2019 as per Emergency Regulations," the statement said.
"The order specifies that the base criterion for identification is the ability to see the face of an individual clearly."
A burqa is a garment worn by some Muslim women that covers the entire body, with mesh over the eyes. The niqab is a full-face veil with an opening for the eyes.
At least one Sri Lankan hotel reportedly has banned facial coverings after the attacks.
Police think the National Tawheed Jamath, a local extremist group, may be behind the Easter bombings, but ISIS has claimed responsibility. A link between the attackers and the terror group has not been proven.
The country is still 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. On Friday night, 10 civilians, including six children, were killed along with six suspected terrorists after a shootout between police and alleged militants.
