Libyan security officials say a bomb thrown near the Algerian Embassy in the country's capital has wounded three security guards.

The officials say the bomb came from a passing car and struck the guard's station and damaged a diplomatic vehicle Saturday.

No group immediately claimed responsibility for the attack. The security officials spoke on condition of anonymity because they were not authorized to brief journalists.

The attack comes as Libya remains mired in chaos since the overthrow and killing of dictator Moammar Gadhafi in 2011.

Libya has two rival governments, each backed by an array of militias that have effectively split the nation. The internationally recognized parliament was pushed out of the capital, Tripoli, when a previous parliament backed by rival Islamist militias refused to cede power.
