Quito: U.S. intelligence from inside Ecuador was used to plan a 2008 bombing by Colombian troops that killed a top FARC guerrilla chieftain inside Ecuadorean territory, the government said on Thursday, Reuters informs.

A 130-page report prepared by the Ecuadorean government says U.S. forces then based in the Pacific coast town of Manta helped Colombian troops target Raul Reyes, No. 2 commander of the Revolutionary Armed Forces of Colombia (FARC).

The March 2008 bombing, carried out in an Ecuadorean border area called Angostura, triggered a diplomatic crisis in the region. Ecuador and Colombia are just now reestablishing diplomatic ties severed by Quito after the raid.

Ecuador has since ended its Manta cooperation agreement, prompting Washington to sign a deal with Colombia in October allowing U.S. forces to carry out anti-drug operations from seven Colombian military bases.
