Riot police used pepper spray and stun grenades against hundreds of Greek soccer fans who tried to break through a police cordon at a Europa League game Thursday. The young fans hurled rocks and gasoline bombs at the police.

Three people were hurt and four detained from the violence that happened during and after a match between Panathinaikos and Lazio at Athens' Olympic Stadium. Before the game, police had intervened to separate rival fans.

The three injured fans were treated with first aid. Their injuries were not considered serious.

Panathinaikos and Lazio are in Group J of the European competition, with Tottenham and Maribor.
