EL ALTO, Bolivia (AP) — Bolivia's pro-government supporters and security forces confronted protesters loyal to former president Evo Morales in a street melee Sunday, the second such violent escalation this week as fears grew of further unrest in the Andean nation.

The protesters and counterprotesters hurled firecrackers, homemade explosives and stones at each other across a dusty sprawl in the city of El Alto, while riot police unleashed tear gas into the crowds. At least eight people were injured, Bolivia's health ministry reported.
