Aid workers kidnapped from Kenya camp released

Dadaab refugee camp in Kenya is home to more than 450,000 Somalis

Four aid workers seized from a refugee camp near Kenya's Somali border have been released and are safe after an operation by Kenyan and Somali forces.

The Norwegian Refugee Council (NRC) said it was "relieved and pleased" its staff were free.
The foreigners, from Canada, Norway, Pakistan and the Philippines were ambushed last week. A Kenyan driver was killed in the attack.
Many aid groups have left the Dabaab camp after a recent rise in abductions.
The NRC workers were travelling in a convoy last week when they were ambushed by gunmen in Dadaab, which houses more than 450,000 Somalis.
Somali and Kenyan forces launched a joint rescue operation after receiving intelligence as to the hostages' whereabouts.
"They are safe in our hands, they have been freed," Kenyan army spokesman Cyrus Oguna was quoted by AFP as saying.

He said one of the kidnappers was killed during the operation.
The NRC said it would release further details later on Monday.
"The Norwegian Refugee Council is relieved and pleased to confirm that our four abducted colleagues are found and released. The families have been informed," the NRC said.
Somalia has had no effective central government since 1991, and has been wracked by fighting ever since - a situation that has allowed piracy and lawlessness to flourish.
Gunmen last October seized two Spaniards working for Medecins sans Frontieres (Doctors Without Borders). They are still being held hostage in Somalia.
