Colombia’s raid Saturday in Ecuador in an attempt to capture the FARC rebels has degenerated into rising tensions as Venezuela and Ecuador has sent troops to the Colombian border and shut down their embassies in Bogota.

”The Colombian government has never wanted to disrespect or violate the sovereignty or integrity of the sister republic of Ecuador,” Colombia’s foreign minister, Fernando Araujo said.

The Colombian incursion claimed the lives of 18 FARC rebels, including the life of the 59-year-old FARC chief commander Raul Reyes.

According to the Ecuadorian President Rafael Correa, Colombian leader Alvaro Uribe said that the raid aimed at pursuing the guerilla militants based in Ecuador. But President Correa said that the rebels were killed in their sleep, Voice of America informs.

Colombian officials have disclosed the fact that the documents found in a camp where the top rebel leader was killed contain information regarding alleged ties between the FARC rebels and Ecuadorian President Rafael Correa, Reuters reports. The respective documents include contacts about political proposals and local military commanders.

Police Commander Gen. Oscar Naranjo said the documents were found in computers belonging to Reyes, and link the FARC commander to a Correa government minister, Gustavo Larrea.

“These documents raise the question of what the relation of Ecuador's government is with a terrorist organization,” Naranjo said in a news conference.

The allegations were totally dismissed by Correa. He called for the immediate meeting of the Organization of American States and the Andean Community of Nations.

Ecuador’s Interior Minister Fernando Bustamante said that “We are not going to accept such a thing. It is very easy to say something based on evidence that has not been scrutinized publicly or internationally.”

There are fears related to possible military clashes at the Venezuelan-Colombian border, as President Chavez has already deployed tanks and fighter planes to the border.

The FARC (the Revolutionary Armed Forces of Colombia) are considered by the U.S. and E.U. officials a terrorist group, engaged in drug trafficking and kidnapping. The rebels are said to hold 40 political hostages, including the French-Colombian politician Ingrid Betancourt, which they intend to free in exchange of their fellow rebels in governmental jails. More than 700 people are believed to be kept hostages for ransom.

Due to the U.S. billion-dollar financial support, President Uribe has succeeded in driving back the FARC militants to remoter areas, an operation that clearly reduced the number of bombings and attacks orchestrated by the FARC.
