A suicide attack in an eastern Afghan province Wednesday killed 14 people and wounded 18 others, police said.
The suicide bomber targeted a police bus that was coming from a training academy, said Alisha Paktiawal, police chief of Nangarhar province. The dead included 10 police.
Militants often target security forces in Afghanistan. An explosion in April killed three police academy trainers in Nangarhar.
Afghan President Hamid Karzai condemned the attack in a statement and blamed it on terrorists intimidated by the growing strength of Afghan security forces.
