The United States will continue to pressure Venezuelan President Nicolas Maduro until he understands his days are �numbered,� Secretary of State Mike Pompeo said on Sunday.

Pompeo�s comments came the day after clashes between activists trying to deliver U.S-backed humanitarian aid into Venezuela and troops loyal to Maduro. Two people were killed in a clash on the Brazilian border and some 300 injured in other violent clashes near Colombia.

Pompeo tells �Fox News Sunday� and CNN�s �State of the Union� that the Trump administration will continue to support opposition leader Juan Guaido. Pompeo declined to rule out U.S. military force as an option, but he added, �There�s more sanctions to be had, there�s more humanitarian assistance I think that we can provide.�

Maduro has blocked such aid at the border and resisted calls to step aside and let Guaido take power.

Pompeo says the U.S. will seek �other ways� to get food aid to Venezuelans.

Vice President Mike Pence travels to Bogota, Colombia, on Monday for an emergency meeting on Venezuela with foreign ministers from more than a dozen, mostly conservative Latin American and Caribbean states. Guaido said on Saturday he would meet with Pence in Bogota.
