Colombo: Maldives President Abdulla Yameen on Wednesday declared a state of emergency in the Indian Ocean atoll nation.
"(The) Maldives declares state of emergency for a period of 30 days starting 12 p.m. (0700 GMT) on Wednesday," presidential spokesman Muaz Ali tweeted, reports Xinhua news agency.
The declaration by President Abdulla Yameen gives security forces sweeping powers to arrest suspects.
It comes two days before the planned protest by the country's main opposition, the Maldivian Democratic Party (MDP), BBC reported.
MDP leader Mohamed Nasheed was jailed in March after a widely criticised conviction under anti-terror laws.
The Maldives has been rocked by political infighting in recent weeks, with vice-president Ahmed Adeeb arrested in connection with an alleged plot to assassinate the president.
Yameen narrowly escaped injury when a blast struck the boat he was using to return home from the airport late last month.
Adeeb has been charged with high treason.
