A seven-month-old girl has been rescued from the debris of a building that collapsed four days ago in the Kenyan capital, Nairobi.

The six-storey residence came down in heavy rain, killing at least 22 people.

Dozens of others are still thought to be buried under the rubble, but hopes of finding more alive are fading.

The building had been earmarked for demolition. Its owner will appear in court on Tuesday charged with manslaughter.

Samuel Karanja Kamau was arrested on Monday. Officials say he did not have permission to rent out the building's 119 rooms.

Kamau has not yet commented on the allegation.

About 135 people have been freed so far from the collapsed building, local media report.

The Kenya Red Cross said the baby girl was found in the rubble at 04:00 local time (01:00 GMT), in a bucket wrapped in a blanket.

She appeared dehydrated, but had no visible injuries, it added. She was rushed to hospital for treatment.

She was originally reported to have been one-and-a-half years old.

The BBC's Emmanuel Igunza in Nairobi says the child's rescue is a badly needed miracle as recovery efforts enter their fourth day.

More bodies were retrieved overnight.
