Dozens of angry youths clashed with police in Paris suburbs on Monday for the second night in a row, injuring more than 70 police officers.

The youths threw Molotov cocktails and fired guns at police officers.

The riots where triggered by the deaths of two teenagers who crashed their motorcycle into a police car in Villiers-le-Bel on Sunday night.

In the first night of violence in two Paris suburbs 21 police officers were injured.

More than 70 police officers were injured last night in what was the second night of violence.

Five of them were in a critical condition. One officer was hit in the shoulder with a hunting rifle and a journalist was injured, Guardian Unlimited reports.

The riots spread to other four suburbs although of the French President Nicolas Sarkozy’s appeals for calm.

Residents compare the riots with the ones in 2005, when for three weeks young people devastated cars and clashed with the police, night after night. These incidents were said to be rage over unemployment, discrimination and the sense of exclusion from French society, L.A. Times reports. Those riots were also triggered by the deaths of two young people who got electrocuted while they fled police.

According to police official Patrice Ribeiro, last night’s clashes were more intense than those from 2005. He also said that police are up to a “genuine urban guerrillas with conventional weapons and hunting weapons."

A preliminary investigation of the accident on Sunday night, carried by local public prosecutor shows that the motorcycle turned into the way of the police car and that police officers called for an ambulance immediately.

Still, angry residents say that police officers left the scene of the crash without giving any help to the teenagers.

A judge ordered a manslaughter inquiry due to the conflicting reports and another inquiry was set by a separate internal police to see if the police officers failed to help the teenagers.

Last night’s clashes began at 7:30 p.m. with 160 police officers occupying the streets and firing rubber bullets at the groups of youths.

At midnight the local library was on fire as well as a McDonald’s restaurant and a police station.

François Hollande, the head of the opposition Socialist party, said that the clashes are the result of "a social and political crisis".

He added: "Promises were made. We want to see the results. How long have we been talking about a 'plan for the suburbs?"
