Late Libyan leader Muammar Gaddafi's son Hannibal has been freed after being briefly kidnapped by an armed group in Lebanon, security sources say.

A court in Libya sentences Col Muammar Gaddafi's son, Saif al-Islam, and eight others to death over war crimes linked to the 2011 revolution.

Libya's official government bans Bangladeshi workers from entering the country because many try to travel to Europe by boat illegally, a government spokesman says.
