Separate attacks have targeted a US military base in the Somali town of Baledogle and a European military convoy in the capital, Mogadishu.
A bomb attack was followed by small arms fire at a base operated by US special forces on Monday, a security source told Reuters news agency.
The Somali armed group al-Shabab claimed responsibility for the attack at the US base.
Italy’s defence ministry in a statement confirmed that an Italian military convoy was hit by an explosion. No injuries had been reported so far, the defence ministry said.
