PROLIFERATION TOPS CZECH SUMMIT !

US President Barack Obama is in the Czech Republic for a summit with European Union leaders, with the issue of proliferation top of the agenda.
Mr Obama will outline his vision of a world free of nuclear weapons in a major speech in the capital, Prague.
He will then meet leaders of the 27 EU nations to discuss issues such as climate change and energy security.
The summit comes hours after a controversial rocket launch by North Korea despite international warnings.
Mr Obama condemned the launch, saying that North Korea had further isolated itself from the community of nations, and should refrain from further "provocative" actions.
In his speech in Prague, the US president is expected to call for a global summit on nuclear security and the forging of new partnerships to prevent the spread of nuclear weapons.
His first trip to Eastern Europe, 20 years since the end of the Cold War, was supposed to be the highlight of the Czech presidency of the EU.
But his official engagements there have been scaled down in the wake of Prime Minister Mirek Topolanek's resignation late last month, after losing a no-confidence motion.
Mr Topolanek - who has also described Mr Obama's stimulus plan as "the road to hell" - will remain in office until a new cabinet is appointed or fresh elections are held.
Nuclear fears
Mr Obama arrived in Prague late on Saturday from the Nato summit in Strasbourg, where he secured pledges from European nations to send more troops to Afghanistan to provide security for elections in August

The Obama effect reaches Nato

He is now due to turn his attention to the threat posed by nuclear proliferation in a speech outside Prague castle.
"To achieve a global ban on nuclear testing, the Obama Administration will work to bring the Comprehensive Test Ban Treaty into force," the White House said in a statement, referring to an agreement which would ban all nuclear explosions for any purpose.
It added that Mr Obama would also seek Senate ratification of the CTBT, which cannot currently come into effect as nuclear powers such as the US and China have not ratified it, and India and Pakistan have not signed it.
In his speech, Mr Obama is also expected to seek to negotiate a new international treaty that "verifiably ends the production of fissile materials for nuclear weapons," the statement said.
Speaking in Strasbourg on Friday, the US president said he would "lay out an agenda to seek the goal of a world without nuclear weapons".
He would also address issues such as the security of nuclear material and the trade in illicit weapons, he said.
"Even with the Cold War over, the spread of nuclear weapons or the theft of nuclear material could lead to the extermination of any city on the planet," Mr Obama said.
His speech comes days after he and Russian President Dmitry Medvedev - meeting on the sidelines of the G20 summit in London - agreed to reopen negotiations about reducing nuclear warheads.
They aim to produce a new arms control treaty to replace the Strategic Arms Reduction Treaty (Start) that expires at the end of the year.
Under Mr Obama's predecessor, George W Bush, tensions arose between the two sides over America's plan for a missile defence shield, parts of which would be stationed in Poland and the Czech Republic.
The new US administration is currently reviewing the plans, which are meant to counter nuclear attacks from countries like Iran and North Korea but which Moscow sees as a threat.
After his speech Mr Obama will meet EU leaders, before flying to Turkey for the final stop of his European tour.
Ahead of his arrival several hundred people gathered in Prague to protest against the missile shield. Further protests are expected on Sunday.
