Two of 18 Turkish workers kidnapped by gunmen in Baghdad this month have been freed in the southern city of Basra

Two of 18 Turkish workers kidnapped by gunmen in Baghdad this month have been freed in the southern city of Basra, Turkish and Iraqi officials said on Wednesday.

The men were among 18 employees of major Turkish construction firm Nurol Insaat kidnapped on September 2 in the Sadr City area of north Baghdad, where they were working on a football stadium project.

The Turkish ambassador to Iraq, Faruk Kaymakci, said that two workers had been released and were found near a Turkish company's premises in Basra.

"They are in good health," he told AFP. "They said the other 16 were also in good health as of yesterday (Tuesday)."

The Basra police issued a statement saying that the two men were found late on Tuesday, while the Turkish foreign ministry spokesman also confirmed their release.

An unknown group claimed the kidnappings in a video posted online last week and issued a list of demands it said Ankara must fulfill for them to be freed.
