Tripoli - Libya said it had arrested 32 supporters of the country's former leader Muammar Gaddafi in connection with bombings that killed two people in the capital, Tripoli, earlier on Sunday.
An official from Libya's Supreme Security Committee, which has been supervising security matters since Gaddafi's overthrow and death last year, said the 32 had been part of an organised network.
Connections between the group and the attacks, near security and interior ministry facilities, "have been established", the official told Reuters.
Three car bombs exploded near interior ministry and security buildings in Tripoli on the eve of the anniversary of the fall of Tripoli to rebel fighters.
Ambulances and firefighters rushed to the scenes of Sunday's blasts in residential areas in central Tripoli, and large numbers of police were deployed to cordon off the sites and remove the charred vehicles and other debris.
They were the first fatal attacks of their kind since a revolt led to Gaddafi's overthrow and death last year after 42 years in power.
