Masked gunmen have abducted 30 Shia Muslim men who were travelling by bus through central Afghanistan, according to local authorities. 

The men, members of the minority Hazara ethnic group, were taken on Monday evening in Zabul province, on the road between the western city of Herat and Kabul.

Hazara Shia Muslims are often the target of sectarian violence at the hands of Sunni Muslim groups in Pakistan and Afghanistan.

"Our driver saw a group of masked men in Afghan army uniform signalling him and he thought they were soldiers so he stopped," said Nasir Ahmad, an official with the Ghazni Paima bus company, told AFP news agency.

"The gunmen took 30 Hazaras away with them."

Ahmad said the kidnappers took only the men on the two buses and released the women and children travelling with them.

No one immediately claimed responsibility for the abductions, but kidnappings for ransom by bandits, local militias and the Taliban are common in Afghanistan.

Interior ministry spokesman Sediq Sediqqi said the police were "doing everything to ensure their safe release".
