Rescuers are trying to free a woman who was found alive six days after a building collapsed in the Kenyan capital Nairobi.

The teams are making space in the rubble as they attempt to release the victim who has been speaking to medics waiting at the scene to treat her.

The number of people confirmed to have lost their lives in last week's disaster has risen to 33, while 80 others are still missing, say officials.

A baby, who is nearly six months old, was rescued on Tuesday, raising hopes more survivors would be found.

The infant was discovered unharmed in a washbasin after the six-storey housing block came down.
