Sri Lankan President Gotabaya Rajapaksa fled the country on Wednesday, hours before he was due to step down after a people's uprising over a devastating economic crisis ended his family's powerful grip on the island nation.
As news of the president's flight spread, thousands of people gathered at the main protest site in Colombo chanting "Gota thief, Gota thief", referring to him by a nickname.
Hundreds of others stormed the prime minister's office, demanding the resignation of Prime Minister Ranil Wickremesinghe.
Wickremesinghe, in his capacity as acting president has declared a state of emergency and imposed curfew in the western province, the prime minister's media secretary Dinouk Colombage told Reuters.
The president's flight brings an end to the rule of the powerful Rajapaksa clan that has dominated politics in the South Asian country for the last two decades.
Protests against the economic crisis have simmered for months and came to a head last weekend when hundreds of thousands of people took over key government buildings in Colombo, blaming the Rajapaksas and their allies for runaway inflation, corruption and a severe lack of fuel and medicines.
Government sources and aides said the president's brothers, former prime minister Mahinda Rajapaksa and former finance minister Basil Rajapaksa, were still in Sri Lanka.
Gotabaya Rajapaksa, his wife and two bodyguards left the main international airport near Colombo aboard a Sri Lankan Air Force plane early on Wednesday, the air force said in a statement.
A government source and a person close to Rajapaksa said he was in Male, the capital of the Maldives. The president would most likely proceed to another Asian country from there, the government source said.
Rajapaksa was due to step down as president on Wednesday to make way for a unity government after protesters stormed his and the prime minister's official residences.
Mahinda Yapa Abeywardena, the speaker of Sri Lanka's parliament, told Reuters partner ANI he was yet to receive any communication from Rajapaksa. A source in the ruling party said the president would send in a letter of resignation later on Wednesday.
That would make Wickremesinghe the acting president, although he has also offered to resign. If he does, the speaker will be the acting president until a new president is elected, as per the constitution.
Protest leaders, however, say the prime minister is allied to the Rajapaksas and have warned of a "decisive fight" if he does not resign by Wednesday afternoon.
"If we don't hear of the resignation of the president and the prime minister by the evening, we may have to gather back and take over parliament or another government building," said Buddhi Prabodha Karunaratne, one of the organisers of recent protests.
"We are strongly against the Gota-Ranil government. Both have to go."
Amid the economic and political chaos, Sri Lanka's sovereign bond prices hit fresh record lows on Wednesday.
The US Embassy in Colombo, which is in the central district of the city, said it was cancelling consular services for the afternoon and for Thursday as a precautionary measure.
