According to the sources, the suicide bomber joined the line alongside other young people who came to the military recruit office. The bodies of 15 people were found at the scene of the blast, with more than 10 others sustaining injuries.

Al-Shabaab radical Islamist group (banned in Russia) claimed responsibility for the attack. According to the Somali Guardian news website, the terrorists said the suicide bombing killed 32 recruits, another 40 were injured.

This is the seventh terrorist attack in Somalia over the past 24 hours, the military said.

Al-Shabaab, which is affiliated with al-Qaeda terrorist group (banned in Russia), has been waging an armed struggle against the government of Somalia and is still controlling large areas in the southern and central parts of the country.

In May, the United States decided to renew strikes against the group's positions in order to combat the growing threat that al-Shabaab poses to US partner forces.
