MOGADISHU, July 1 (Reuters) - Al Shabaab militants shot dead three Somali soldiers in the capital Mogadishu on Tuesday, their fourth attack since the start of the Ramadan fasting month that the Islamists have threatened to target.

Sheikh Abdiasis abu Musab, al Shabaab's spokesman for military affairs, said they carried out the attack in the southern Mogadishu district of Afarta Jardiin.
