The rebels were searching for passengers with ink-stained index fingers, a sign that they had cast ballots in Thursday's election, he said.

A vote-monitoring group said Saturday that one of their observers witnessed that militants chopped off fingers of two voters in southern Kandahar province, the birthplace of Taliban movement.

In order to avoid multiple voting, the voters were expected on Thursday to dip their fingers into bottle of indelible ink, a measure that turned ominous for the voters as Taliban could easily identify them in volatile southern region.

The militants repeatedly threatened Afghans not to take part in Thursday's presidential and provincial elections, warning they would slit throats and chop off fingers of anyone who voted.

The Taliban fighters conducted more than 130 attacks, including firing dozens of rockets and unleashing numerous suicide bombers on polling sites to disrupt the vote, which was the second in history of the country.
