Berlin - Separating three protesters from a German railtrack was slow work Saturday for a team of police after the anti-nuclear activists used an ingenious method to lock themselves in place.

During the morning, the two men and a woman fixed their hands and arms inside tubes inside a huge lump of concrete under the track, according to fellow protesters.

A trainload of nuclear waste was unable to pass along the line. Obstructing tracks is one way the anti-nuclear movement shows its opposition to the transport of waste.

Abuja - Decrying a return to fighting in the east of the Democratic Republic of Congo, German President Horst Koehler Saturday urged all African nations to put an end to their disputes.

"This must have an end," said Koehler, speaking at the German- sponsored fourth Africa Forum in the Nigerian capital of Abuja. He said the news from DR Congo was "particularly disappointing."

As the forum met, the leaders of DR Congo and Rwanda were at a meeting in Kenya to try to negotiate an end to the fighting in eastern DR Congo.

Berlin - Five past winners of the Nobel Economics Prize generally favour an increase in regulation of financial markets, the German news magazine Der Spiegel reported Saturday.

The magazine said it asked them for comment before key world leaders hold a G20 meeting on the crisis in Washington.

Those asked for a recipe were four US academics, Joseph E Stiglitz, Paul A Samuelson, Edmund S Phelps and Robert E Lucas and one German, Reinhard Selten.

Lucas was quoted saying the best solution would be a competitive banking system where deposits were guaranteed by the state.

Amman - Jordanian Prime Minister Nader Dahabi flew to Doha Saturday for a two-day state visit to Qatar designed to open a new chapter in relations between the two Arab countries which have not been on good terms over the past decade.

Jordan's efforts to improve ties with Qatar started last week when the chief of the Jordanian royal court Nasser Lawzi took a message from King Abdullah II to Qatar's ruler Sheikh Hamad Bin Khalifa Al Thani.

London - Ever since Roman Abramovich bought Chelsea in the summer of 2003, the sight of Chelsea at or near the top of the English Premier League table has become a common one.

Back-to-back Premier League successes in 2005 and 2006 soon followed but after an impressive first season under Jose Mourinho they were never loved by fans for their style, which was pragmatic, at best.

Until now, that is.

Berlin - Thousands of anti-nuclear demonstrators were trying Saturday to obstruct a tightly guarded convoy of spent nuclear fuel on its way to a German waste dump.

Near the warehouse in Gorleben in the northern German countryside where many tons of radioactive waste are stored, some 14,500 demonstrators attended a protest rally accompanied by bands, police said.
