The number of those injured during Sunday’s blast on Thika Road in Nairobi is 86, the government has said.
Reports had earlier indicated that 70 people were injured during the incident.
47 were admitted at the Aga Khan University Hospital, 32 at Kenyatta National Hospital and seven at St Francis Community Hospital in Kasarani.
A tweet from the Kenya National Disaster Operation Centre, @NDOCKenya, said:
“Of the 86 admitted with injuries, 67 have been treated and released, mostly for soft tissue injuries.”
The Red Cross has also set up a tracking centre at the Kenyatta National Hospital and can be contacted through the emergency number 0715820219.
The government has urged Kenyans to report any suspicious activity as the fight against terrorism is stepped up.
Three people were killed in near-simultaneous explosions on the Thika Superhighway on Sunday.
Five matatu bus crew have been charged with failing to screen passengers in connection with the explosions in ill-fated buses on the Thika Road on Sunday.
They were charged with failure to prevent a felony, namely murder and were ordered to deposit personal bonds of Sh5 million each with two sureties of similar amounts.
The prosecution told the Makadara Chief Magistrate Emily Ominde that the crew failed to screen passengers “thereby allowing the buses to be blown up by an unknown passenger.”
Mr Robert Gakuru and Mr Joshua Wambugu, both drivers, and Mr James Munene, Mr Geoffrey Mwangi and Mr Antony Muthee who were conductors all denied the charge.
The case will be heard on July 17. A mention was set for May 20.
At least three people were killed and 62 wounded when two improvised bombs exploded on buses in the capital.
Of the 62 wounded, 20 were admitted in critical condition.
Sunday’s twin attacks were on two buses packed with commuters along Thika Road, headed to Githurai and Mwiki from the city centre.
The explosions came a day after two blasts at the Kenyan coast killed four people.
An explosion went off on a 52-seater bus named Jeean at the Homeland bus stop opposite Garden City, outside Homeland Inn near Kenya Breweries at around 5.05pm.
A second explosion went off inside a Mwisacco bus at the Kasarani underpass at around 5.29pm.
