BOGOTA (AFP) -- Tensions between Colombia, Ecuador and Venezuela reached a new high Sunday after Bogota launched a cross-border raid against Colombian rebels in Ecuador, killing the second-ranking official of the FARC group.

Raul Reyes of the Revolutionary Armed Forces of Colombia (FARC) was killed Saturday in the raid on a jungle camp on the Ecuadorian side of the common border.
In response, Ecuadorian President Rafael Correa recalled his country's ambassador to Bogota ""for consultations"" and warned the action might result in ""ultimate consequences"" because of ""the offense"" suffered by his country.
The Ecuadorian Foreign Ministry said it had lodged a formal protest with Bogota demanding an explanation, while Correa said that Colombian President Alvaro Uribe was either ""misled"" by his military or ""lied to the Ecuadorian government.""
From Caracas, Venezuelan President Hugo Chavez warned of a war if Colombia carried out raids against the FARC on Venezuelan territory.
""President Uribe, think about it long and hard. You had better not get the idea of doing this on our territory because it would be a 'causus belli', cause for a war,"" Chavez said in his first reaction to the raid.
""This is something very grave which is unprecedented in our lands,"" Chavez said, adding that he had telephoned Correa ""and we agreed to keep exchanging information.""
""The government of Colombia acknowledges having made an incursion, violating the (air) space of a neighboring country in an irresponsible way. This is worrisome,"" Chavez said.
Uribe telephoned Correa to talk to him about the operation, but it was unclear if they spoke before or after the raid. Correa said he had deployed troops to the area to ""verify"" what had taken place.
Reyes was in a rebel camp located 1.8 kilometers (a mile) from the Ecuadorian-Colombian border when the air force began bombing shortly after midnight, Colombian Defense Minister Juan Manuel Santos told a news conference.
Colombian ground troops were then deployed into the guerrilla hideout to secure the area, Santos said. A total of 17 guerrillas and one soldier were killed in the operation.
""It is the heaviest blow ever dealt against this terrorist group,"" Santos said.
Reyes, 59, whose real name was Luis Edgar Devia, was a union leader working for Swiss food giant Nestle in the southern department of Caqueta when he joined FARC in the 1970s.
His killing was a major coup for Uribe, who has taken a hard stance against the 17,000-strong FARC, South America's biggest insurgent group which has bedeviled successive governments since the 1960s.
It was the first time that one of the seven members of FARC's secretariat, or leadership council, was killed in combat.
After the death of FARC's ideological leader Jacobo Arenas in 1992, Reyes became the group's international face, taking the group's message abroad. In this capacity, he met with U.S. government representatives in Costa Rica in 1997.
Pro-government lawmakers and the country's influential Roman Catholic Church expressed hope that his death would prompt the FARC to release its hostages and negotiate a peace agreement.
""The FARC must seriously begin a peace process that puts an end to this long nightmare that Colombia has experienced,"" said Monsignor Fabian Marulanda, secretary of the Colombian Episcopal Conference.
Reyes's death came three days after the FARC unilaterally released four former lawmakers who had been held hostage for years, handing them to the Venezuelan government and the Red Cross in a snub to Uribe.
