CARACAS (Reuters) - Venezuelan opposition leader Juan Guaido said on Saturday that President Nicolas Maduro’s use of troops to violently block the entry of humanitarian aid meant he would propose to the international community that all options remain open to oust Maduro.

“Today’s events force me to make a decision: To formally propose to the International Community that we must have all options open to secure the freedom of our country, which fights and will keep fighting,” Guaido said on Twitter.

Troops had turned back foreign aid convoys from Venezuela’s border using teargas and rubber rounds on Saturday, killing at least two protesters.
