Somalia's Islamist al Shabaab militants, who have used Twitter to announce assassinations and bombings, are back on the microblog service two weeks after their account was suspended.
"Our new account will function like the one they closed," a spokesman who declined to be named said on Tuesday.
Al Shabaab's previous official Twitter account was suspended around Jan 24, days after group, which is aligned with al-Qaeda, used the social media site to threaten to kill two Kenyan hostages.
The group tweeted a link to a video of the abducted civil servants and threatened to kill them unless the Kenyan government released all Muslim prisoners in its jails.
Twitter rules say threats of violence are forbidden but the site declined at the time to comment on why al Shabaab's account, which had thousands of followers, had been suspended.
Al Shabaab's Somali- and Arabic-language Twitter accounts were never closed.
