The US State Department expressed concern for an aggression faced Friday by US Ambassador in Caracas William Browfield.

A group of pro-government protesters attacked the diplomat with eggs and tomatoes when he was visiting a sports facility in Coche, southwest Caracas, where he was scheduled to make a donation for a junior baseball team sponsored by the Baltimore Orioles team.

According to US embassy in Caracas, Brian Penn, the demonstrators rejected Brownfield's presence and impeded him to leave for half an hour, news agency Efe reported.
