An explosion at a busy bus station in the centre of Kenyan capital city of Nairobi has left three persons dead and at least eighteen others injured, Press TV reports.

The explosion took place on Monday in Nairobi where an earlier blast had hit a club wounding at least 14 people.

No group has claimed responsibility for the assaults.

The explosions came following warnings of retaliation by the Somali-based al-Shabab group after Kenyan forces crossed into Somalia's southern territory in the hunt for militants.

Kenyan military intervention in Somalia more than a week ago was spurred by recent spate of kidnappings in Kenya, blamed by Nairobi on al-Shabab militants.

Four European women, including two Spanish humanitarian aid workers, were abducted in Kenya over the past weeks.

One of the abductees, a cancer-stricken 66-year-old French woman, who had been spirited away in a Kenyan resort island earlier this month, died in the hands of her captors in Somalia last week after reportedly being deprived of the medication she had been sent.
