A Kenyan official says three more people have been rescued after being trapped for six days in the rubble of a collapsed building, bringing the number of those rescued Thursday to four.

Nairobi's police chief Japheth Koome said two women and a man were rescued late Thursday after a woman eight months pregnant was rescued earlier in the day. The rescue of the four people comes as the death toll from the collapse of the seven-story building rose to 36 and 70 people remain missing.

A nearly six-month-old baby was rescued on Tuesday, which raised hopes that more survivors would be found. The infant was found unharmed in a washbasin four days after the building collapsed.
