At least six people have been killed
in explosions in the Kenyan capital, Nairobi, officials say.
Several people were also injured in the blast, which took place in the
Eastleigh suburb of the city.
Eastleigh is known as "Little Mogadishu" because it has a large Somali
population.
"Police
are securing the area for emergency response services," said the Kenya National
Disaster Operation Centre.
The cause of the blast is unknown but there have been several grenade attacks
in Eastleigh, including one in December last year that killed four people.
Although no group said it was behind that attack, many blamed it on the
Somali militant group al-Shabab.
Four members of the group were behind the four-day siege at a shopping centre
in Nairobi last September, in which 67 people died.
The
militants had stayed in Eastleigh before launching the
attack.
Kenya
has several thousand troops in Somalia, helping the UN-backed government tackle
al-Shabab, who are linked to al-Qaeda.
