A Somali pirate on Sunday threatened to kill any Korean sailors taken hostage in the future to avenge the Korean Navy's killing of eight pirates on Friday when it stormed a hijacked vessel in the Indian Ocean and rescued the crew, the Chosun Ilbo reports.

"We never planned to kill, but now we shall seek revenge," a pirate who identified himself as Mohamed told Reuters by phone. "We shall never take a ransom from Korean ships; we shall burn them and kill their crew."
