Somalia: Six dead in Mogadishu refugee camp blast

The victims included a security guard and a local aid worker, witnesses said.

Meanwhile, two major medical centres run by medical charity Medecins Sans Frontieres (MSF) near the site of the blast have closed.

The charity said it had taken the decision after two MSF workers, a Belgian administrator and Indonesian doctor, were killed last month.

The bomb exploded just 20 minutes after a team of international journalists had left the Mogadishu camp.

They had gone to Mogadishu to see the situation six months after the famine was first declared.
