Legendary US spy planes in operation over North Korea

U-2, the legendary spy plane used during the Cuban missile crisis in 1962, is now monitoring the situation in North Korea.

Three planes flew out of a US base near the South Korean capital of Seoul on a surveillance mission.

Tensions continue to soar in the Korean peninsula and the US is now concerned that its combative approach to the situation may have exacerbated the crisis.

Meanwhile, North Korea issued a warning to the UK saying they could not guarantee the safety of British diplomats after April 10 in the event of a conflict.
