SEOUL (Reuters) - A South Korean fighter jet crashed southeast of Seoul on Thursday, leaving two pilots presumed dead, the air force said.

The jet was unrelated to U.S.-South Korean military drills taking place in South Korea this month.

The annual joint military exercises were delayed by about a month for the Winter Olympics and to help create conditions for a resumption of talks between North and South Korea.

The F-15 jet was returning to base from conducting air maneuvers when it crashed, an air force official said. He did not comment on the possible cause.
