"We are still investigating the bad news," spokesman of the ministry Michael Tene said here on Friday.
Earlier, AFP news agency reported a gunman killed two foreign aid workers after opening fire at a Doctors Without Borders compound in Mogadishu on Thursday (Dec 29).
Somali security forces arrested the man, a witness told AFP, while a police officer identified him as a Somalian employee with Medicins Sans Frontieres (MSF - Doctors Without Borders).
The shooting is the latest attack on humanitarian officials in the Horn of Africa nation, one of the most dangerous places in the world for aid workers and one of the regions that needs them most.
MSF confirmed that the incident took place inside its compound in the Somali capital but was unable to comment on casualties.
"We confirm that a serious shooting incident has taken place in the MSF compound in Mogadishu. At this point we don`t have more information about the scale and the extent of this incident," the organization said in a statement.
"MSF is doing everything it can to ensure the security of its staff."
The police officer said the gunmen may have been fired, while local MSF staff said he had quarreled with his employers the day before.
Staff at Medina hospital said one man, who they described as a Westerner, was dead on arrival.
His colleague, whom they identified as an Indonesian, had been hit in the thigh, with the bullet piercing an artery and causing heavy bleeding.
"The second victim died at the hospital as doctors were trying to save him," Dumiya Ali, deputy director of the Medina hospital said later. The victim had already lost a lot of blood when he arrived at the hospital, she said.
MSF said it would probably issue another statement on Friday. (*)
