Deadline missed


North Korea's missile development and its pursuit of nuclear weapons have been a growing cause of concern among its neighbours.


Under a deal agreed at six nation talks in Beijing in February North Korea agreed to begin shutting down its nuclear programme by April 17.


However, that deal has been held up in a dispute over frozen North Korean funds held in a Macau-based bank, the Banco Delta Asia.


"If they were fired towards the Sea of Japan, it may be a
sign that they are unhappy that the Banco Delta Asia funds are
not being transferred," Toshimitsu Shigemura, professor at Waseda
University, told Nippon Television after Friday's reported missile tests.

"Last time, the missiles were long-range, but this time they
are short-range, which may mean they don't mean to surprise too
much. They only want to attract attention."


In July last year North Korea test-fired a series of missiles in, including its latest long-range model, known abroad as the Taepodong-2, which experts believe could reach parts of the United States.


In October it conducted its first-ever test of a nuclear weapon.


However, intelligence experts in the region and in the US say North Korea is still some way off developing a nuclear warhead capable of being placed on a missile.
