Police say a German development worker has been kidnapped by suspected Islamic extremists in northeastern Nigeria.

Deputy Superintendent Othman Abubakar says witnesses report the man was taken at gunpoint from his car in Gombi, in Adamawa state on Wednesday. Northeastern Nigeria has been under a military state of emergency since May 2013.

Separately state radio in neighboring Cameroon reported this week that Boko Haram fighters have kidnapped two teenage children of a leading Muslim cleric from their home near the border with Nigeria.

Boko Haram rarely claims responsibility for kidnappings of foreigners but ransoms are believed to have earned it millions of dollars in the past two years.

The extremists attracted international condemnation for the abductions of more than 200 Nigerian schoolgirls who have been in captivity for three months.
