The Somalian government claims to have blocked several websites that it claims are aiding in the propagandizing of the jihadist group al-Shabab.
It has issued a warning against posting what it describes as frightening and deceptive remarks, as well as any content that can incite jihadist attacks.
Recent weeks have seen some military progress against al-Shabab by pro-government forces with help from abroad.
The gang nonetheless continues to launch periodic bomb strikes.
Hassan Sheikh Mohamud, the president of Somalia, vowed an all-out assault against the Islamist extremist group shortly after taking office in June.
