Angry Libyans demanding reforms block prime minister office, Foreign Ministry building

A security official in Libya says dozens of angry protesters have demonstrated in front of the prime minister's office and the Foreign Ministry building over poor government performance and widespread corruption.

The protesters placed chunks of concrete blocks in front of Prime Minister Ali Zidan's office Sunday. Zidan later met his visiting Algerian counterpart in another location.

The official said protesters also demonstrated in front of the Foreign Ministry demanding the resignation of the government. He said others prevented employees of the telecommunication company from entering their offices.

The security official, who spoke on condition of anonymity because he is not authorized to brief journalists, said the demonstrators later dispersed peacefully.

Libya has been roiled by unrest since the ouster in 2011 of longtime dictator Moammar Gadhafi.
