Gunmen kidnapped four Catholic priests in southern Nigeria, a local official in the state of Delta told AFP on Wednesday.
Delta State spokesman Andrew Anyamaka said the kidnapping took place Tuesday between Ido and Delta states in the south.
"They were kidnapped when they were on their way to Akboma, returning from Delta state," he said, adding that police and local security forces were looking for the insurgents.
A church official confirmed the incident, which comes less than three weeks after the kidnapping of five Catholic nuns in Delta state.
The nuns were released two weeks later, and a suspect was arrested, according to Anyamaka. He did not confirm whether a ransom had been paid.
Several sources confirmed that the nuns were the proceeds from burial ceremonies in southeastern Nigeria when they were kidnapped by gunmen who opened fire on their cars, injuring two other nuns.
In January, the bishops of Nigeria denounced a wave of kidnappings for ransom in the country.
