Ecuador says US troops stationed in the country were indirectly involved in a Colombian bomb attack on Ecuadorean territory in March 2008. A report by the Ecuadorean truth commission says the attack would not have been possible without intelligence supplied by US forces at a military base in the town of Manta.

Twenty-five people were killed in the bombing, including the FARC guerrilla movement's second-in-command Raul Reyes.

The incident sparked a diplomatic crisis between Colombia on one side and Ecuador and Venezuela on the other. Ecuador has since broken off its military cooperation with the United States, which was aimed at combating the drug trade.
