PARIS — More than 300 people have been arrested in France since the Euro 2016 soccer tournament began last week, and 24 are being deported after violent clashes between fans, the French authorities said Thursday. The violence has marred the start of the event and heightened security concerns in a country that is still under high alert for terrorist threats.
Bernard Cazeneuve, the French interior minister, said in a statement on Thursday that 323 people had been arrested in connection with instances of violence, theft and vandalism since the tournament began on June 10, and that 196 of them had been temporarily detained.
