Two Turkish engineers and an Afghan kidnapped three days ago near the capital Kabul (search) have been freed, a security group for aid workers said Monday.

The Afghan NGO Security Office (searchgave no details of the release of the three men, who were abducted Friday. Afghan officials said the men, who were helping dig wells, were taken in connection with a land dispute.

"It would appear that this was a domestic incident deriving from a local dispute and did not involve any of the usual extremist elements," Nick Downie, the head of the security office said in a statement.

It wasn't immediately clear where the three men were Monday and who had been holding them. Afghan government officials, who had been negotiating for the men's release, could not be immediately reached for comment.

Authorities are searching for two Indian road workers kidnapped by heavily armed men in southern Afghanistan on Saturday.

A Turkish engineer abducted by Taliban in late October was released unharmed a month later.
