SEOUL, South Korea (AP) — North Korea on Saturday continued its string of rocket and missile firings, launching three short-range projectiles into the waters off its east coast ahead of a major holiday celebrated by both Koreas, a South Korean defense official said.

The projectiles flew about 210 kilometers (130 miles) before landing in the water, said the official, who spoke on condition of anonymity because of office rules. It wasn’t immediately clear what sort of projectiles they were.
