North Korea on Wednesday launched a long-range rocket which Japanese authorities said passed over its southern island chain of Okinawa. It was the second launch this year, after a failed attempt in April.
North Korea has said the rocket is aimed at putting a satellite in orbit, but much of the international community sees the launch as a thinly veiled ballistic missile test, banned by UN resolutions.
Key dates in North Korea's missile programme:
Late 1970s Starts working on a version of the Soviet Scud-B (range 300 kilometres or 186 miles). Test-fired in 1984
1987-92 Begins developing variant of Scud-C (500 km), Rodong-1 (1,300 km), Taepodong-1 (2,500 km), Musudan-1 (3,000 km) and Taepodong-2 (6,700 km)
August 1998 Test-fires Taepodong-1 over Japan as part of failed satellite launch
