Ebola Crisis: 'Time for talking is over' - Liberia's Sirleaf

The president of Liberia, Ellen Johnson Sirleaf, has appealed to all countries to help fight the Ebola outbreak in West Africa.

In a letter recorded for the BBC, she says Ebola has managed to bring Liberia to a standstill, killing more than 2,000 people in just over six months.

She says the whole world has a stake in the fight, as the disease respects no borders.
