The Taliban has threatened to launch a fresh wave of violence at next month's presidential run-off in Afghanistan, and is urging voters to boycott the poll.
Campaigning has opened for the second round of voting, to be held on 7 November, the BBC reports. Incumbent President Hamid Karzai faces his main challenger, former foreign minister Abdullah Abdullah.
The first vote, in August, passed off without major violence though there were sporadic attacks by Taliban militants.
The Afghan electoral commission is trying to stop the widespread fraud that hit the first-round of voting.
