Tens of thousands of supporters and opponents of the Egyptian President Mohammed Morsi have staged rival rallies around the country ahead of the first anniversary of his coming to power on Sunday. Egyptian security officials say that in Alexandria, a young American man was killed during the protests. Jane O'Brien has more details.

According to Egyptian security officials, the young man was stabbed in the chest during anti-government protests, although some reports suggest he may have been wounded by gun pellets. He was apparently using a mobile phone camera near an office of the ruling Muslim Brotherhood party which was being attacked by opponents of President Mohammed Morsi. He was taken to a military hospital where he died from his injuries. Egyptian state television described the man as a photojournalist, but Alexandria security chief Amin Ezzedine said he worked at a US cultural centre in the city.

President Obama has arrived in South Africa after playing down speculation that he might visit Nelson Mandela in hospital. In comments on board Air Force One, Mr Obama said the last thing he wanted was to be in any way obtrusive. James Copnall reports.

Barack Obama will meet his South African counterpart Jacob Zuma and is expected to make a major speech during his stay here. But there is no doubt his visit will be overshadowed by Nelson Mandela. The global icon is still critically ill in hospital. Mr Obama has already said he is not looking for a photo op or to get in the way of Mr Mandela's family. Winnie Madikizela-Mandela, Mr Mandela's ex-wife, said she felt it would not be right for Mr Obama to visit the hospital given Mr Mandela's condition.

European Union leaders have agreed to open membership talks with Serbia by January in recognition of its efforts to improve relations with its former province of Kosovo. The president of the European Commission, Jose Manuel Barroso, described the decision as historic. Chris Morris reports.

For much of the 1990s many countries in Europe regarded Serbia as a prior state, the driving force behind the wars that tore the Balkans apart. But now Serbia is taking a decisive step towards eventual membership of the European Union. The decision to begin accession talks by January is a reward for Serbia's efforts to improve relations with Kosovo, its former province which broke away and then declared independence in 2008. The EU has also decided to start work on what's called an association agreement with Kosovo itself covering a variety of economic and political ties.

The father of a fugitive CIA analyst Edward Snowden says he's reasonably confident his son will return to the United States to face trial for espionage. Lon Snowden was speaking to the American TV channel NBC. Jonny Dymond reports from Washington.

"I love him”, says Lon Snowden of his son Edward. “And I want to communicate with him. I don't want to put him in peril.” The two men have not spoken since Edward fled to Hong Kong after he leaked classified information about America's huge worldwide covert surveillance operations. Lon Snowden says he believes that his son would return voluntarily to the United States which has charged him with espionage if he had a guarantee that he’d not be held prior to any trial and that he'd not be in anyway gagged.

One of the world's largest media empires, Rupert Murdoch’s News Corporation, will be divided in two shortly. The corporation's entertainment arm, which includes Hollywood movie studio, will split from its publishing business when US financial markets close. Here is our business correspondent Mark Gregory.

Rupert Murdoch spent his career building a global media group that last year had revenues of $34bn. Now at the age of 82 he is breaking it up. The stated logic is financial, but there is also an unstated logic behind this split-- the division lessens the risk that the highly profitable movie-making and television arm of the business will be contaminated by the fallout of a phone hacking scandal that's engulfed Mr Murdoch's British newspapers.
