Violence at a Berlin school has prompted calls in Germany to overhaul the country's education system and provide better integration for immigrant children.
Pictures of hooded pupils pelting journalists with heavy cobblestones and police officers lining the entrance of the Ruetli school in the heavily Turkish and Arab Neukoelln district of Berlin have filled primetime news since Thursday.
Four weeks ago, teachers at the Ruetli school sent a desperate letter to state authorities asking for help and the closure of their current school."
Any help for our school could only improve the situation," the teachers wrote, saying they had been attacked by pupils and that many would only enter a class room with their mobile phones switched on to be able to call for assistance immediately.
"Looking ahead, the school as it is should be dissolved in favor of a new one with a completely different setup," the teachers added.
