McCarthy said there are no specific known threats to the city, but critical response vehicles and heavily-armed Hercules teams have be redeployed as a precaution.
Fifty-nine people are dead and at least 175 are injured after gunmen stormed into a mall in Nairobi Saturday, according multiple reports.
As of Sunday morning, several hostages are still being held in the mall.
An Al-Qaeda-linked Somali militant group has claimed responsibility for the attack on Twitter.
