A district police chief and his bodyguard have been killed after a chain of bomb blasts targeted officers in the Afghan capital Kabul.

No-one immediately claimed responsibility for the explosions, which were all caused by so-called sticky bombs – devices attached to vehicles which are remotely detonated or set off by timers.
