INDIGENOUS activists in Bolivia have blamed the government for an alleged attempt to assassinate former president Evo Morales.

Mr Morales reports surviving a bid to kill him in the coca leaf-growing region of Chapare on Sunday after unidentified heavily armed men dressed in black opened fire on his car. 

He was not injured in the alleged attack, which quickly became the latest flashpoint in a struggle between the former leader and current President Luis Arce.
