U.S. President Donald Trump said he does not rule out any action in connection with the situation in Venezuela, where the speaker of parliament and opposition leader Juan Guaido declared himself acting president of the country.

“We are not considering anything, but all options are on the table,” Trump said.

In turn, Venezuelan President Nicolas Maduro said that the U.S. is behind what is happening in the country. According to RT, Maduro said that the U.S. attempted a coup attempt in Venezuela.

January 10, Maduro took office as Venezuelan leader for the second time. The U.S. and most South American countries refused to recognize his victory in the election, while the opposition called him an usurper. On Wednesday, at the urging of Juan Guaido, mass demonstrations against Maduro began in Venezuela, which have already resulted in human casualties.
