At least 10 journalists were injured, several of them seriously, when a bomb ripped through Somalia's national theatre in Mogadishu.
The blast, for which the militant insurgent group Al-Shabaab took responsibility, killed four people, including two of the nation's top sports officials.
The attack occurred five minutes into a speech by the prime minister, Abdiwelli Mohamed, at a ceremony marking the anniversary of Somali national television.
Witnesses said they believed a suicide bomber had carried out the attack.
Reporters who were covering the ceremony told the Committee to Protect Journalists (CPJ) that four journalists suffered serious injuries.
They were Said Shire Warsame of Shabelle TV, Ahmed Ali Kahiye of Radio Kulmiye, Ayaan Abdullahi of S24 TV and Hamdi Mohamed Hassan of Somali Channel TV.
Deeqa Mohamed of the state-run Radio Mogadishu suffered shrapnel wounds and the five other journalists also reported to be injured were Mohamed Noor Mohamed Sharif of Radio Bar-kulan, Somali National Television staffers Mikail Hassan Ali and Abdulkadir Mohamed Hassan, and freelance journalists Suleiman Sheikh Ismail and Mulki Hassan Haile.
The CPJ's east Africa consultant Tom Rhodes said: "Somalia remains the region's most dangerous nation for the press."
Members of Al-Shabaab are believed responsible for the 2012 killings of journalists Ali Ahmed Abdi in Galkayo and Abukar Hassan Mohamoud in Mogadishu.
