North Korea fires record number of missiles in a single day

North Korea fired at least 17 missiles on Wednesday, South Korea's military said, causing Ulleung Island to the east of the mainland to be placed under an air raid warning.

It is the first time an apparent test had landed so near South Korean waters, prompting South Korea to issue the rare alert and launch its own missiles in protest.

Residents on Ulleung Island were told to take refuge in underground shelters and await updates when the alarm was raised.

Authorities in Seoul said one of the missiles landed just 57 kilometers (35 miles) east of the country's coastline.

A short time later, the South Korean military said it had fired three air-to-ground missiles in the same area in response.
