Supporters of Somali president clash with opponents

Reuters witnesses heard gunshots erupt in capital and one saw four military vehicles positioned in one place in the Fagah area of Mogadishu.

A former Somali leader accused Mohamed of orchestrating an attack by soldiers on his home on Sunday (April 25) as splits deepened over an extension of the incumbent's term in the volatile Horn of Africa nation.

Former Somali President Hassan Sheikh Mohamud's accusation against Mohamed on Twitter - which did not include details or proof - came as factions within Somalia's security forces exchanged gunfire in the capital Mogadishu.
