Libyan officials say a car bomb has exploded near a police station in the country's second largest city, wounding three people.

Authorities say the blast Sunday in the Mediterranean city of Benghazi heavily damaged the front of the police station.

In September, U.S. Ambassador Christopher Stevens and three other Americans died in an attack on the U.S. diplomatic post in Benghazi.

The new Libyan government is struggling to control armed individuals and militias that gained power during an armed conflict that ousted Libyan leader Moammar Gadhafi last year. Benghazi was the birthplace of the revolt.
