The Kenyan flag

Nairobi, Kenya -

A roadside bomb in the Kenyan capital wounded at least eight people, the latest in a string of attacks, police said Wednesday.

“We have confirmed eight casualties who have all been rushed to hospital,” Nairobi police chief Moses Nyakwama told AFP.

“The explosion was caused by a roadside bomb which had been placed in a hole in the ground by the roadside,” he added.

The blast, which occurred at around 7:30pm local time (1630GMT) with the streets crowded as people returned home from work, reportedly happened near a supermarket in the largely ethnic Somali neighbourhood of Eastleigh.

Three of those wounded are in a critical condition, Kenya Red Cross officials said.

“No arrests have been made yet, and investigations are already under way,” Nyakwama added.

Just last month at least seven people were killed and many more wounded in a bomb attack on a bus in the same district.

Kenya has suffered a string of attacks often blamed on Al-Qaeda-linked Shebab militants since it sent its troops, now integrated into an African Union force, into Somalia.

The troops seized the Shebab bastion of Kismayo in September, a key southern Somali port, prompting warnings of retaliation from both the insurgents and their Kenyan supporters.

No one had claimed responsibility immediately for the attack Wednesday. - Sapa-AFP
