Libya's first independent TV says a hand grenade was hurled at its building in the eastern city of Benghazi.

An employee at the Libya Al-Hurra, Tareq el-Issawi, said on Friday that a colleague was injured in the attack overnight outside the TV's offices.

Libya Al-Hurra is the first independent TV channel to emerge from the uprising that toppled Moammar Gadhafi.

Libya's culture ministry strongly condemned the attack and attempts to intimidate media.

It was the latest violent incident in Benghazi, Libya's second largest city and the site of an attack last year on the U.S. consulate that killed Ambassador Chris Stevens and three other Americans.

This week, 31 people were killed in protests against militias in Benghazi.
