The main militant group in Nigeria's Niger Delta region says it has rescued two German workers seized by unidentified gunmen last month.
The Movement for the Emancipation of the Niger Delta sent out an e-mail Thursday saying its fighters had rescued the two workers, both staff members of the construction firm Julius Berger.
It said the two workers would be freed shortly.
There was no immediate confirmation of the report from the company or the German embassy.
The two workers were kidnapped July 11 near Port Harcourt, the hub of Nigeria's oil industry.
Julius Berger suspended its activities in the Niger Delta after the kidnapping.
MEND later threatened attacks against the company if it did not halt operations in the capital, Abuja.
Militant groups frequently attack oil pipelines and kidnap foreign workers in the Niger Delta. The militants say they are fighting so impoverished residents of the region will get a greater share of the region's oil revenue.
The attacks have cut Nigeria's oil production by more than 25 percent over the past two years.
