Ecuador and Venezuela have since cut diplomatic ties with Colombia, and on Wednesday Correa called Alvaro Uribe, the country's president, "a psychotic liar".
Ecuador claims Colombia violated its sovereignty by carrying out the strike on its territory.
Should Hugo Chavez be involved in mediation efforts with Colombia's Farc?

Correa, however, said the resolution was not enough.
"The OAS resolution pleases us. We are pleased, but not satisfied," he said after his meeting with Chavez.
"This isn't going to cool down until the aggressor is condemned."
Wednesday's resolution called for Jose Miguel Insulza, the OAS secretary-general, to lead a delegation to both Ecuador and Colombia to ease tensions, but stopped short of explicitly condemning the assault.
The US was the only OAS member to offer Bogota unqualified support.
Bogota's claims
Colombia has accused both Chavez and Correa of aiding the Farc, labelled by Washington as a "terrorist" organisation, and said this was shown by documents found on a laptop seized at the bombed rebel camp.
It said that documents found on Reyes after the attack indicated that Venezuela gave Farc $300 million.

"I don't think there is a risk of war. The Colombian government has been very clear it won't use force," Santos said on Thursday during a visit to Brussels for talks with EU officials.
"It won't fall into the game of provocation."
Santos said Colombia was justified in launching the raid because it had repeatedly asked Ecuador, as well as Venezuela, in vain to take action against Farc camps on their territory.
Santos said his government was prepared to take further measures to solve the situation on condition that the Farc is not allowed to set up camps close to Colombia's borders.
