Costa Rica issues warning as volcano erupts

Costa Rica has issued an emergency alert after the eruption of Turrialba volcano in the centre of the country.

Ash from the eruption has gone as far as the Costa Rican capital of San Jose.

The volcano has not spewed lava since the 1800s but there are concerns that this eruption could be a precursor to larger eruptions.
