Two Nigerians and five foreign workers including three Australians, a New Zealander and a South African are released four days after a deadly attack on their convoy. 
The men, who work for Perth-based mining company Macmahon Holdings, were in a group driving on the outskirts of the city of Calabar when they were attacked by gunmen on Wednesday. Their driver, a Nigerian man, was killed, according to the Guardian News. 
The company said in a statement late on Sunday night the men including three Australians, two Nigerians, a New Zealander and a South African had been released. 
Australia's foreign minister, Julie Bishop, confirmed the news. 
No ransom was paid, according to assistant superintendent Irene Ugho, spokeswoman for the Cross River state police. Ugho did not offer details about how the men were freed. 
She said: "The success of the rescue exercise was due to the combined efforts of the security agencies and the support of the state government."
