In a statement to the Novi Sad-based "Gradjanski list" paper, Kasza wondered if Hungarians should continue living "under such pressure, in a country like this", but added that he considered as reassuring the strong reactions of Serbia's president and prime minister.
Serbian Prime Minister Vojislav Kostunica said that the attack on the leader of the Federation of Vojvodina Hungarians was also an attack on the state of Serbia and that measures would be taken to find and punish the perpetrators as soon as possible.
Serbian Interior Minister Dragan Jocic visited Kasza on Tuesday afternoon, stating that the intention of the attackers was to destabilise inter-ethnic relations in Vojvodina and cause anxiety among members of minority communities.
The attack was also condemned by the president of the Executive Committee of the Croatian National Council, Lazo Vojnic Hajduk, who said that the messages sent by the attackers were taking the Serbian society back to the recent past.
The explosion outside Kasza's house caused minor damage to the facades and windows of Kasza's and his neighbour's house. No one was injured.
Kasza, one of the most vocal opponents of the regime of former Yugoslav president Slobodan Milosevic, has been representing the interests of the Hungarian minority in Serbia over the past 15 years.
The attack is one of the most serious incidents directed against Vojvodina Hungarians since last year's attacks which drew strong EU criticism.
