遭尼日利亚歹徒绑架的两名德国人被释放

Two German men seized by gunmen while swimming in a Nigerian river have been freed after six days.

两位德国人因在尼日利亚一条河流里游泳而被持枪歹徒绑架，六天之后这两位德国人才被释放。

The men, aged 45 and 55, were kidnapped（绑架） on April 18 in the oil-producing south east of the country.

"Both our German countrymen are safe and sound（安然无恙） and again free," Germany's foreign minister, Guido Westerwelle, said in a statement.

Dozens of foreigners have ben kidnapped in the Niger Delta, which is home to Africa's biggest oil and gas industry.

The men were abducted（诱拐，绑架） in Abia state after going swimming in the Imo River.

Referring to the oil city capital of neighbouring Rivers State, Mr Westerwelle added: "They are doing well and are in safe hands in Port Harcourt."

The abduction is the second of foreign workers in Nigeria in the last 10 days. No group has said it carried out the latest kidnapping.
