Kenya President Uhuru Kenyatta has visited the site in Huruma where a building collapsed killing 12 people and injuring more than 120 others.
The building located in the Huruma residential estate in the Kenyan capital Nairobi collapsed on Saturday morning.
The seven-storey building melted down after heavy rains.
The president says atleast 12 people died while more than 120 were left nursing injuries.
The Red Cross managed to rescue about 121 people by midday.
The rainfall in addition has caused landslides, washed away houses and flooded roads.
Police told KTN that 14 people died in the Nairobi rains, including those in the collapse.
The Huruma neighbourhood is a poor district on the outskirts of Nairobi made up of narrow streets, meaning firefighters struggled to get to the scene and were delayed by large crowds.
President Uhuru Kenyatta last year ordered an audit of all the buildings in the country after a spate of collapses.
“I instructed officials of the Interior Ministry and the County Government to undertake an immediate survey of all the houses in the area to find out those, which are at risk of collapsing,” Kenyatta said in a statement.
He said those in houses that are at risk of collapsing should be ordered to move to safer grounds.
“I also instructed the Inspector General of the National Police Service to take immediate action to identify and arrest owners of condemned buildings who have ignored directives by the National Construction Authority.”
