A suicide car bomber has killed 10 people in an attack on Western troops in the Afghan capital, days before a presidential election.



More than 50 people were wounded in the explosion, which came despite heightened security ahead of Thursday\'s polls.

Militants have threatened to disrupt the vote in which Hamid Karzai is tipped to be re-elected president.
