BOGOTA (Reuters) - The United States targeted Venezuelan President Nicolas Maduro's government with a fresh round of sanctions on Monday after violence blocked the delivery of food and medicine to the economically devastated country during the weekend.

The Treasury Department said it was sanctioning four pro-Maduro state governors, blocking any assets they control in the United States as Vice President Mike Pence said the aid blockage had steeled the United States' resolve to support opposition leader Juan Guaido.
