Youths wielding iron bars beat up two riot policemen patrolling a rough housing project in a southern Paris suburb, police officials said Wednesday. One officer was hospitalized with a double fracture of the skull during Tuesday night's incident in Corbeil-Essonnes, a police source said. His colleague reportedly sustained facial and body injuries. Police were called in to disperse the gang of up to 30 youths who stoned the unmarked police car as it patrolled the area, police officials said. The police got out of their car, were encircled and attacked. Some of the youths were armed with iron bars, according to reports. No arrests were made following the incident, police said. "These youths fear nothing," a police union official said on LCI television.
