According to police sources, a man lunged at them with a long-bladed knife at Paris's Gare du Nord train station early Monday.
A 30-centimetre (12-inch) knife with ACAB (All Cops Are Bastards) scrawled on the blade was used to attack two police officers on patrol at the busy station, which is the terminus for trains from London, according to a police source who did not want to be identified.
