A suicide bomber attacked an Afghan army bus in the capital, Kabul, on Sunday, killing three people and wounding at least 10, police said.
The attack, the latest in a worrying upsurge of violence in Kabul and around Afghanistan, was claimed by the Taliban.
"The number (of victims) might change. An investigation is ongoing abut the incident," said Hashmat Stanikzai, the chief spokesman for police in Kabul. (Reuters)
