Had a call from my daughter around lunch time saying that someone had released some sort of gas in her school and a number of students and teachers have been taken to hospital with breathing difficulties. The rest of the students have all now been sent home after being let out in small groups. The school is crawling with the police, and people in ¨white coats¨. There's nothing in the the news so far. Might just be a prank I suppose, someone's twisted way of marking the Auschwitz day?
