Libya has released a South Korean man two months after he was detained for allegedly being involved in Christian missionary work in the Libyan city of Benghazi, a Seoul official said Friday.

The man, who is only identified by his surname Lee, was arrested on Feb. 10, along with three other foreign nationals, on suspicion of being a Christian missionary and distributing books about Christianity.

"Lee was released on April 11," the foreign ministry official said on the condition of anonymity.

South Korea's foreign ministry had been in close consultations with Libyan authorities to release Lee, the official said.
