Afghan candidate survives Kabul bombs

The front-runner in Afghan's presidential election, Abdullah Abdullah, has survived a bomb attack targeted at his convoy in Kabul. Police say there were several casualties when two blasts hit the site of a rally. Mr Abdullah says some of his bodyguards were among the injured. The run-off round of the presidential election takes place next week. No group has said it carried out the attack but the Taliban have repeatedly threatened to target the poll campaign. The first blast was detonated by a suicide bomber in a car, a Kabul police spokesman told the BBC's Bilal Sarwary. The spokesman said the second explosion was probably caused by what he described as a "sticky bomb". Pictures from the scene show a plume of smoke rising into the air.
