Venezuelan forces fire tear gas at opposition protesters -Reuters images

Venezuelan security forces fired tear gas at opposition demonstrators blocking a highway in capital Caracas on Wednesday, amid growing pressure on socialist President Nicolas Maduro, Reuters images showed.

Opposition leader Juan Guaido earlier declared himself interim president of the crisis-stricken country, receiving backing from the United States and several Latin American governments.
