Nairobi — A blast near a military air base in Kenya's capital city has wounded at least 8 people.
Witnesses say three of the 8 are in critical condition after the blast Wednesday evening.
The blast went off in a Somali neighborhood of Nairobi known as Little Mogadishu. Kenya has seen a series of small-scale explosions over the last year, many from grenades.
Kenyan troops moved into Somalia in late 2011, prompting al-Shabab militants in Somalia to vow revenge attacks inside Kenya.
Al-Shabab sympathizers are suspected in many of the blast attacks, though authorities have not clearly linked all the attacks to al-Shabab or its sympathizers.
