A landmine blast killed a woman working with the United Nations to register voters for Afghanistan's elections on Thursday, the latest attack blamed on Islamic militants determined to derail the polls.
Four other poll workers in the same vehicle were wounded in the second fatal attack in less than two weeks on women registering female voters in the eastern province of Nangarhar.
It came just hours after the interior minister said security should be sufficient for polls this year, while the UN urged Nato to speed the dispatch of more peacekeepers to ensure this.
The woman died and her driver was in serious condition after their vehicle hit the mine in Khogyani district, UN spokesman Manoel de Almeida e Silva said.
