Prosecutors said Friday a series of coordinated attacks on French prisons were carried out by drug traffickers, with at least one suspect thought to have ties to a notorious cartel. Attackers in April struck at several jails and other facilities across France, torching cars, spraying the entrance of one prison with automatic gunfire and leaving mysterious inscriptions. Maxence Gallo, a lawyer for one of the suspects, says the attacks were 'a cry for help'. IMAGES AND SOUNDBITES
