SEOUL, May 21 (Reuters) - The ballistic missile launched by North Korea on Sunday reached an altitude of about 560 kilometres (348 miles), a South Korean military official said.

The missile resembled North Korea's Pukguksong-2 type, an upgraded, extended-range version of its submarine-launched ballistic missile, the official said by telephone.

South Korea's foreign ministry condemned the launch saying in a separate statement that the missile launch was "reckless and irresponsible", dashing the new South Korean government's hopes for peace.

New South Korean liberal President Moon Jae-in took office on May 10 pledging a more moderate approach to the North.
