The Kenyan Red Cross says two people have been killed and eight wounded after a blast in downtown Nairobi.

Friday evening's blast was the second in three days. A blast Wednesday near a military base wounded eight people.

Both explosions 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 media reported that a member of parliament was wounded in Friday's attack.

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.
