Hungary told Serbia Tuesday that it is ordering a 30-day closure of the border crossing between the two countries following clashes between refugees and Hungarian police.
Refugees were met with tear gas and water cannons from Hungarian police as they tried to breach a 110-foot barbed-wire fence.
Under a new series of laws in effect Tuesday, it is illegal to cross the border from Serbia into Hungary. Hungarian authorities say they have arrested 519 refugees attempting to do so and convicted one Iraqi man, who a judge banned from returning for one year, Hungarian media reported. He must also pay $70 in court costs.
