Official: Pirates may try to avenge SKorean rescue

South Korea says it has intelligence that Somali pirates may attack South Korean ships in retaliation for the killing last week of eight pirates by Korean commandos.

Defense Minister Kim Kwan-jin told reporters Monday that South Korean ships sailing in the Gulf of Aden must strengthen safety measures to prevent such an attack. He didn't elaborate on the intelligence.

Last Friday, a team of South Korean commandos launched a daring raid on a hijacked cargo ship in the Arabian Sea, rescuing all 21 crew members. Five pirates were captured and eight killed in the rescue.

The Defense Ministry quotes Kim as saying that South Korea is considering bringing the five captured assailants to South Korea to have them stand trial.
