Gunmen shot dead a Kenyan policeman and wounded two others in an overnight attack on the Kilifi coastal region, local government officials said Friday.

"We lost a police officer in the attack," said Kilifi county commissioner Albert Kobia. "They were attacked by a gang that opened fire at the station."

The attack, some 55 kilometers (35 miles) northeast along the coast from the main port of Mombasa, is the latest in a string of killings in Kenya in recent months.

There was no immediate claim of responsibility, but previous attacks have been blamed on extremist groups accused of links to Somalia's Al-Qaeda-affiliated Shebab rebels, or to a separatist movement called the Mombasa Republican Council (MRC).

Shehab insurgents have also carried out repeated revenge attacks since Kenya invaded Somalia in 2011.
