A car bomb has (exploded) outside the former foreign ministry in the Somali capital, Mogadishu, killing five people including the suicide bomber.
The attack came as Kenya's defence and foreign (ministers) were holding talks nearby with the Somali government.
Kenya sent troops to Somalia on Sunday to fight Islamist al-Shabab militants it (blames) for a spate of kidnappings.
There have been (contradictory) statements from both countries about the presence of the Kenyan force.
A Somali government general, Yusuf Dhumal, told the BBC Somali Service on Tuesday from the (village) of Taabto, that his troops were with the Kenyan force heading towards an al-Shabab-held town of Afmadow, 120km (75 miles) from the border.
Al-Shabab, which controls much of southern Somalia, has denied carrying out any abduction and has warned of attacks in Kenya unless the troops withdraw.
Kenya's defence and foreign ministers, Yusuf Haji and Moses Wetangula, were at the city's main airport for talks with Somali government officials, when the car bomb exploded on a busy street about 2km (more than one mile) away.
