Austria letter-bomb

Vienna's mayor, Helmut Zilk, one of Austria's most outspoken proponents of minority rights, was seriously injured yesterday in the fifth letter-bomb attack in three days, AP writes from Vienna. Later, police defused a letter-bomb addressed to the parliamentary leader of the Greens, Madeleine Petrovic. Government and police officials have worried that the surge in letter-bombs is linked to anti-foreigner sentiment. All of the recipients have had links to refugees or minority issues.
