Members of the Ecuadorean police force attacked the country's president, Rafael Caldera, in an eruption of political unrest over austerity measures today, hospitalising the left-wing leader.
Mr Correa told local media by phone that police protesters were hunting for him in the building and would be responsible if he was hurt. Some of the president's supporters then descended on the hospital and hurled stones at police outside.
Foreign Minister Ricardo Patino has called on supporters to march with him to save their trapped leader.
"President Correa has said that there are people trying to get in from the roof and attack him," Patino told a large crowd outside the presidential palace.
"I want to invite the brave people here below to go with us to rescue the president."
Ecuador, an Opec member of 14 million people, has a history of political instability. Street protests toppled three presidents during economic turmoil in the decade before Correa took power.
Correa, a socialist ally of Venezuelan President Hugo Chavez, said his rivals were plotting a coup against him. Earlier, he was
stunned by an exploding tear gas canister as he tried to speak to demonstrators.
Visibly furious, he earlier confronted police demonstrating at the planned budget cuts and challenged them: "Kill me if you want to. Kill me if you have the courage."
As the chaotic scenes unfolded, scores of soldiers took over the main international airport, which was closed to flights, while uniformed police burned tires and blocked some roads in protest at a proposal to cut their bonuses.
Witnesses said there was looting in Quito and in Guayaquil city, and many workers and school students were sent home.
State oil company Petroecuador said operations were unaffected and troops had boosted security at its oil fields.
Messages of support for Mr
Correa flowed in from abroad, with the Organisation of American States and the governments of Venezuela, Chile, Argentina and others backing his government.
Venezuela's government said Correa spoke to Mr Chavez by telephone from the Quito hospital and that Correa had confirmed that the unrest was a coup attempt against him.
Mr Correa is
considering the dissolution of
congress, where members of his own left-wing party are blocking legislative proposals aimed at cutting state costs.
Ecuador's two-year-old constitution allows the president to declare a political impasse, dissolve Congress and rule by decree until a new presidential and parliamentary election can be held. The measure would, however, have to be approved by the Constitutional Court to take effect.
Police apparently led the protests on Thursday but some soldiers joined in solidarity.
"We are demanding that the president revoke the military service law," one soldier at the airport told Reuters, asking not to be named. If he doesn't, protests will continue."
Police in the cities of Quito and Guayaquil protested at their headquarters. Officers in Guayaquil also blocked some roads leading to the coastal city, Ecuador's most populous.
"Respect our rights," the uniformed officers shouted.
Armed forces' head Ernesto Gonzalez said troops remained loyal to Correa. "We are in a state of law. We are loyal to the maximum authority, which is the president," he told reporters.
Central bank chief Diego Borja called for calm and urged Ecuadoreans not to withdraw money from banks.
Peru closed its border with neighboring Ecuador. More than half the 124-member Congress is officially allied with Correa, but the president has blasted lawmakers from his own Country Alliance party for not going along with his proposals for shrinking the country's bureaucracy.
Mr Correa, a US-trained economist, was first elected in 2006 promising a "citizens' revolution" aimed at increasing state control of Ecuador's natural resources and fighting what he calls the country's corrupt elite.
His government alienated international capital markets when it defaulted on $3.2 billion in global bonds two years ago.
Mr Correa declared the debt "illegitimate." Cash has been tight since then as the country relies on multilateral loans and bilateral lending to meet its international financing needs.
