Shoppers and staff at the Westgate Mall in Nairobi's Westlands area were taken by surprise earlier this afternoon as gunmen numbered between five and 10 attacked the building.
The gunmen are reported to have assailed the second floor of the shopping complex where East FM were holding an open event. Reports from within the building are that the gunmen armed with sophisticated weapons started shooting indiscriminately while ordering people to lie on the ground.
Some of the gunmen are said to have had masks on, while others were already in the building mingling with the shoppers before the attack started at about 1pm this afternoon.
Unconfirmed reports have it that some of the shoppers and staff at the mall attempted to escape by jumping from the second floor to the first, getting injured in the process.
Several other people who were in the building at the time of the attack however have been taken hostage by the assailants with some being at the second floor and others at the basement.
Police who responded to the situation however managed to rescue about 20 people who were on the first floor. The rescue operation continues as police urge members of the public to avoid the area.
Inspector General of Police David Kimaiyo and Cabinet Secretary for Interior Joseph Ole Lenku are both on site and have asked people to stop posting alarming images and messages on any media as the police handle the situation.
Members of the press have also been asked to cease live transmission of the situation or contact people still within the premise as this could jeopardize the safety of those yet unharmed and within the building.
