Taliban militants kidnapped the father of Afghanistan's education minister in a central province, while a Predator drone crashed in the country's east, officials said Tuesday.

Two militants on motorbikes seized the father of Education Minister Farouq Wardak in Wardak province's Sayed Abad district on Monday, said provincial governor Halim Fedai.

The minister's family is in contact with the kidnappers, said Sher Wali Wardak, another son of the kidnapped 80-year-old Khoja Mir.

Kidnappings of wealthy Afghans have spiked over the last year, often carried out by criminals and militants seeking money or political leverage.

In eastern Afghanistan, meanwhile, a U.S. Air Force Predator drone crashed Tuesday, U.S. Central Command said in a statement.

"The crash was not due to hostile fire," the statement said. It did not give a reason for the crash.
