Bolivian President Evo Morales has declared a national disaster in the Andean country following heavy rains and flooding that have killed at least 50 people in recent weeks.

Mr. Morales issued the decree Tuesday to release government aid to flooded areas. On Monday, he toured the hard-hit city of Trinidad, where officials have pitched tents to accommodate people fleeing the town's flooded outskirts.

Officials say the flooding has affected some 45,000 families across Bolivia.
