Germany is calling for greater pressure against the Venezuelan government of President Nicolas Maduro to bring about fresh elections.

Foreign Ministry spokeswoman Maria Adebahr said Monday that Germany believes "the pressure on Maduro needs to be increased so as to move in the direction of free, fair and democratic presidential elections."

Adebahr said Germany is consulting with fellow European countries, but would seek to have additional EU sanctions target those close to Maduro "and of course not worsen the dramatic hardship experienced by the citizens of Venezuela."

Government spokeswoman Ulrike Demmer condemned violence at points on the Venezuelan border where opposition figures have been trying to bring in aid shipments.

Demmer said Germany was particularly concerned by "the apparent deployment of militias and groups of thugs to intimidate the population.

The United States is planning new ways to pressure Venezuelan President Nicolas Maduro to give up power and to provide assistance to the people of the economically devastated South American nation.

Vice President Mike Pence arrived in the Colombian capital on Monday and immediately met with Colombian President Ivan Duque. He'll also meet with members of a regional coalition and Venezuelan opposition leader Juan Guaido to discuss the next steps aimed at ousting Maduro.

Pence's appearance before the Lima Group comes two days after a U.S.-backed effort to deliver humanitarian across the border from Colombia ended in violence.

Forces loyal to Maduro fired tear gas and buckshot on activists accompanying the supplies and setting the material on fire. Four people have been reported killed and at least 300 wounded.
