This is a bit biased, the validity of the election has been rejected all over Latin America and Europe too. You are using Telesur as a source when it's funded by the Venezuelan government and acts as a propaganda outlet.

Also, there's a tense error in the translation of Evo's tweet:

Translation: We denounce that the US and the OAS implemented a plan to defeat #Venezuela: Before the election they will carry out violent actions with support by the media and after the elections they will attempt a military invasion with the Armed Forces from neighbouring countries.
