By Rodi Said and Krisztina Than KOBANI, Syria/BUDAPEST, (Reuters) - A Syrian father on Friday buried his wife and his two little boys, drowned as they tried to flee to Europe, while Hungary's leader told Europeans they risk becoming a minority on their own continent. With desperation and anger deepening among people escaping conflict and poverty, around 300 migrants broke out of a Hungarian reception camp while about 200 others scuffled with police on a Greek island. Austrian police also said the driver of a truck found abandoned last week with the bodies of 71 migrants in the back was among a group of people arrested in Hungary.
