Taliban bombers have attacked an
Afghan police convoy outside the capital Kabul, killing at least 30
people and wounding 50 others, officials say.
The bombing was claimed by the Taliban and follows an attack on a bus just over a week ago that killed 14 people.
A Taliban spokesman said that in Thursday's attack, the first bomber attacked one bus and when rescuers began to arrive the second drove an explosives-laden car into their vehicles.
The cadets were returning to Kabul from a training centre in Wardak province and were about to go on leave.
