Serbian handball player Zarko Sesum has suffered eye injuries after being struck by a dart thrown from the crowd during Friday\'s European Championship semi-final against bitter rivals Croatia. \"Someone threw a dart from the stands aimed at Ivano Balic and it hit Zarko Sesum. He\'s in hospital. We fear he\'ll lose his eye,\" Croatian team official Zlatko Skrinjar told AFP. \"The atmosphere and the chants were detestable. They were talking about murders and so on. It\'s sad but expected,\" he added. Serbia qualified for the final of the competition for the first time in the nation\'s history following their 26-22 victory in Belgrade. Serbian police had stepped up security ahead of the clash following an attack by local hooligans on Croatian fans.
