At least one person has died and several others injured after an explosion on a Kampala-bound bus occurred in downtown Nairobi, barely hours after Uganda's Police chief Maj.Gen. Kale Kayihura, issued a Christmas Al-Qaeda terror alert.

The bus, bound for the Ugandan capital Kampala, was stationed on a busy street in downtown Nairobi, a Nairobi police official told AFP speaking on condition of anonymity.

It was not immediately clear whether the explosion was accidental.

Uganda's police chief Monday said he had "strong indications" that Islamist militant groups were planning terrorist attacks there over the Christmas period.

Uganda's Police chief Maj.Gen. Kale Kayihura had told AFP that the threats emanated from the Shebab, a Somali insurgent group which has pledged allegiance to Al Qaeda, and the Allied Democratic Forces, a Ugandan Islamist group.

Uganda in July suffered East Africa's worst attacks in 12 years when suicide bombers struck two Kampala bars, killing 76 people.
