Ecuador has filed a formal protest with Colombia over the violation of its airspace by Colombian military aircraft.
Ecuador's foreign ministry says the protest, which was submitted Friday, concerned an incident last Saturday in the Puerto Nuevo sector, which is located more than 200 kilometers north of the Ecuadorean capital city of Quito.
Ecuador's defense ministry says data from radars proves its airspace has been violated.
Colombian officials deny violating Ecuador's airspace, saying its forces were responding to an attack on a Colombian military installation by FARC rebels operating near the border.
Quito says this is the fourth such incident in the past five months. It says will address the issue during a meeting of a bilateral border commission in April.
