Explosions have rocked Somalia's capital Mogadishu with gunfire also reported as al Shabaab militants launched attacks on Wednesday.
The country's internal security minister said police stations and security check points were targeted during the eruption of violence.
Al Qaeda-linked al Shabaab, which aims to topple the central government and impose its severe interpretation of Islamic law, carries out frequent attacks against the government, including attacking a minibus carrying election delegates last week.
