Kenya official: 3 killed in suspected al-Shabab bus attack

A Kenyan official says three people have been killed when suspected al-Shabab extremists opened fire on a passenger bus in the coastal county of Lamu days before national elections are held.

Coast regional police boss Larry Kieng said Wednesday the bus was traveling from Mombasa to Kipini and was attacked in the afternoon. Kieng says the fighters shot from the bushes and fled once police escorting the bus engaged them.

Al-Shabab in recent weeks has stepped up deadly attacks in Kenya's border counties of Lamu and Mandera. The extremist group based in neighboring Somalia has threatened to disrupt Kenya's elections on Tuesday.

Al-Shabab has carried out more than 100 attacks inside Kenya, calling it retribution for Kenya deploying troops to Somalia in 2011 to fight the extremists.
