Police in Ecuador have arrested three Colombians and an Ecuadorian accused of plotting to kill the country's leftist president Rafael Correa, officials say.
Police were questioning the men after their arrest in the capital Quito, said Attorney General Washington Pezantes. The men were found with photos of the presidential palace and maps of nearby streets, local media reported. Tensions between Bogota and Quito have been high since Colombia raided a rebel camp inside Ecuador in March. Mr Correa, a critic of Washington and ally of Venezuela's left-wing president, Hugo Chavez, had been informed of the plot, Mr Pezantes said. "We don't know the particular details (of the plot), we only know that there were foreigners with contracts to attack the president," he said. Colombia's cross-border raid on 1 March caused one of the biggest diplomatic crises in Latin America in years. The mission killed a senior commander of the Revolutionary Armed Forces of Colombia, Raul Reyes, and more than 24 other guerrillas. The raid prompted Ecuador and Venezuela to send troops to their borders with Colombia. The troops were withdrawn several days later after a meeting of regional leaders in the Dominican Republic.
