Attacks Wednesday morning targeted Libya's privately owned television channel Alassema, according to Agence France Presse.
Broadcasters told AFP that three rocket-propelled grenades were thrown at the Tripoli-based TV station building, leaving one guard lightly wounded.
Gunfire was also heard in the area prior to the grenade explosions, according to one journalist.
Alassema is considered anti-Islamist and was previously attacked last March with gunmen "ransacking offices" and taking employees hostage.
The station has also been accused of "urging people to demonstrate" against the government and the General National Congress, particularly after the GNC decided earlier this month to controversially extend its mandate until December this year regardless of public discontent and criticism against the current GNC leadership.
Libya continues to slide into further chaos as such attacks increasingly become daily occurrences both in the capital and in other areas throughout the country.
