Security forces in Gabon have arrested more than 1,000 people during a second day of violence following disputed Presidential elections.
Three people were killed in clashes in the capital, Libreville.
Security forces cracked down after protesters attacked the National Assembly building late on Wednesday, tearing down its main gate and setting parts of it on fire.
Opposition leader Jean Ping, who is in hiding, said that a presidential guard helicopter had bombed his headquarters and killed two people.
Security forces were surrounding the building on Thursday night and had detained members of the opposition National Union Party inside, a spokeswoman for the party said.
The UN, US and former colonial power France have called for restraint and greater transparency about the results.
