North Korea has fired two suspected ballistic missiles into the ocean off its east coast - according to South Korea and Japan - the latest in a flurry of weapon launches that Seoul decried as "inappropriate" amid the global coronavirus pandemic.

Two "short-range projectiles" were launched from the coastal Wonsan area on Sunday, and flew 230 kilometres (143 miles) at a maximum altitude of 30 kilometres (19 miles), South Korea's Joint Chiefs of Staff reported.
