A French man believed to be directly involved in Friday's multi-pronged Islamist terror attack in Paris that killed 129 and injured 352 is being hunted by authorities, French security officials said.

Abdeslam Salah, one of three brothers believed involved in the killings in central Paris, rented the black Volkswagen Polo used by a group of terrorists who killed at least 89 people inside the Bataclan concert hall, one official said.

One other police official said the manhunt involves at least one suspect. One of the suspect's brothers has been arrested in Belgium and another brother was killed in the attack, the first official said.

Three of the seven Islamist suicide bombers have already been identified as French citizens. At least one of seven other people arrested in Belgium in connection to the deadly attacks is also French.
