'The government of Maldives wishes to also assure all Maldivians and the global community that the safety of all Maldivians and foreigners living in and visiting the Maldives, will be ensured'.
Legal Affairs Minister Azima Shakoor read out the emergency decree on state television, giving security forces sweeping powers to make arrests, and curtailing the powers of the judiciary.
Security forces also arrested former President turned leading opposition politician Maumoon Abdul Gayoom.
The president's main rival urged people not to obey what he called an "unlawful order".
Mohamed Nasheed, the country's exiled former president, called the state of emergency "tantamount to a declaration of martial law in the Maldives". Yameen has defied a Supreme Court decision requiring jailed opposition leaders to be freed, including Gayoom's son Farish, an opposition lawmaker.
"We request the global community, including India, Sri Lanka, the US, Britain, the EU.to do everything in their power to help return power to the people of the Maldives and restore democracy", the statement read.
Since Thursday, worldwide actors, including the United Nations and countries such as India, the USA and the U.K. have been urging the Male government to respect the ruling.
In an apparent response to the statement, the Supreme Court said in a news release that "there are no obstacles in implementing the ruling and releasing political prisoners and that this has been informed to the Prosecutor General's office".
The Supreme Court said the anti-defection ruling was issued as a temporary solution to the constitutional dispute case filed by the state but insisted that the relevant authorities have failed to bring to effect an anti-defection law specified in the ruling. It said their trials were "politically influenced".
The ruling has led to protests by opposition supporters urging the government to obey the order.
In a letter addressed to the worldwide community, Maldives opposition lawmakers appealed for external support in persuading Yameen to end the tense standoff with the country's highest court. When those lawmakers return, Yameen's Progressive Party of the Maldives will lose its majority in the 85-member parliament, which can result in the legislative body functioning as a rival power to the president. "In the spirit of democracy and rule of law, it is imperative for all organs of the Government of Maldives to respect and abide by the order of the apex court", MEA had said. He was given political asylum in the United Kingdom in 2016.
Mr Gayoom was the archipelago nation's president from 1978 to 2008 and is the half brother of the Maldives' current president, Yameen Abdul Gayoom.
Democratic gains in the Maldives have eroded under the leadership of Yameen, who has conducted a crackdown on the opposition and the press.
He had been set to run for re-election this year virtually unopposed, with all of his opponents either jailed or exiled.
Nasheed was sentenced to 13 years in prison after he was convicted of the abduction charge under the Maldives' anti-terror laws in a trial that was widely condemned by worldwide rights groups.
