North Korea 'may have six bombs'

BBC News, Vienna
UN nuclear watchdog chief Mohammed ElBaradei has told US television his agency estimates that North Korea could have up to six nuclear weapons.
Recent reports say North Korea is preparing to test a nuclear bomb.
In an interview with CNN, Mr ElBaradei said Pyongyang had enough plutonium to make five or six nuclear weapons.
He went on to say that his agency knew the North Koreans also had the "industrial infrastructure to weaponise this plutonium".
North Korea announced in February that it had nuclear arms.
Inspectors for the UN's International Atomic Energy Agency (IAEA) have been unable to verify the claim because they were kicked out of North Korea at the end of 2002.
Shunned talks
An IAEA spokeswoman, Melissa Fleming, told the BBC there was no way the agency could know for sure whether North Korea had six bombs.
But she said it would not be surprising if it did.
Pyongyang has shunned multilateral talks on its nuclear programme for almost a year.
Recently, reports have suggested it is preparing to test a nuclear bomb.
Mr ElBaradei has warned that a nuclear test would have disastrous political and environmental consequences.
He has urged Pyongyang to return to the negotiating table.
