Tensions high in North Korea row

---

International tensions have remained high after North Korea said it was expelling UN nuclear inspectors and resuming work on its nuclear programme, reports BBC.
The US has condemned Pyongyang's "provocative threats", saying they were "a step in the wrong direction".
Washington has joined China, Russia, Japan and other countries in urging Pyongyang to return to negotiations.
The row follows North Korea's launch of a long-range rocket on 5 April, which critics say was a missile test.
By contrast, the mood was festive in Pyongyang on Wednesday as the communist nation celebrated the Day of the Sun - the anniversary of the birth of founding President Kim Il-sung.
State media called for unshakeable loyalty to his son, the current ruler Kim Jong-il, and credited the launch as a "historic victory".
North Korea has said it wants to develop its space programme by 2012, which will mark 100 years since Kim Il-sung's birth. It said the launch was a step towards that goal.
Pyongyang's move has been criticised by all the other members of the six party talks - the US, China, Russia, South Korea and Japan.
But the North insists it put a communications satellite into orbit, and reacted angrily to Monday's statement from the UN Security Council condemning the launch.
North Korea's foreign ministry said it was quitting the long-running six party talks on its nuclear programmes and would "not be bound by any agreement reached at the talks".
