Nairobi: A grenade was thrown into a discotheque in Kenyan capital Nairobi early on Monday injuring 14 people, all Kenyans, central Nairobi Police Chief Eric Mugambi said.
"Initial investigations show it is a grenade that was thrown inside" the disco, Mugambi said, adding: "Fourteen people have been injured."
The US embassy in Nairobi had warned on Saturday of an "imminent threat" of attacks possibly targeting foreigners, one week after Kenyan forces crossed into Somalia to hunt down Al Qaeda-linked Shebab fighters.
The embassy cited "credible information of an imminent threat of terrorist attacks directed at prominent Kenyan facilities and areas where foreigners are known to congregate, such as malls and night clubs."
However, the Kenyan police did not immediately link the discotheque attack to this threat.
The red-painted Mwauras disco is in the bustling centre of Nairobi, popular with night-clubbers. A journalist said few signs of damage were apparent from the outside of the building, which was guarded by a dozen police.
The injured were taken to Nairobi's Kenyatta National Hospital. A nurse said six of them suffered "bad injuries on the faces and head" while the rest had "minor injuries on the hands and legs."
