The Supreme Court in Brazil has ruled that it will hear a politically sensitive corruption case against former president Lula da Silva rather than have it dealt with by a federal judge leading an anti-corruption probe. President Rousseff is due to face impeachment proceedings over alleged budget irregularities. She denies wrongdoing. Her supporters are holding rallies in over 30 Brazilian cities including Rio de Janeiro, from where Julia Carneiro reports. “President Rousseff is under mounting pressure, but the government and her supporters here compare the move to impeach her to a coup. Former president Lula said the movement to oust President Rousseff is a threat to democracy and the power is only legitimate through popular vote. Lula is facing corruption allegation and on Thursday the Supreme Court decided that for now investigations into him would have to be conducted by the higher court and not by the prosecutors in charge of the corruption probe that have him temporarily detained earlier this month.”

North Korea dominated early proceedings at a global summit on nuclear security in Washington. After meeting President Xi Jinping of China, President Obama said both were determined to work towards a nuclear free Korean Peninsula and to implementing more sanctions against Pyongyang. “A great importance to both of us is North Korea's pursuit of nuclear weapons, which threatens the security and stability of the region. President Xi and I are both committed to the denuclearization of the Korean Peninsula and full implementation of UN sanctions. So we're gonna discuss how we can discourage action like nuclear missile tests that escalate tensions and violate international obligations.”

Police in the Indian city of Kolkata say it’s unlikely that more bodies will be found in the wreckage of a partially built flyover that collapsed on Thursday.

The government of Monaco has joined an investigation into what it calls a vast corruption scandal implicating a number of multinational oil companies. It said was helping British investigators looking to media allegations that a little known company based in the Principality UNAOIL had delivered millions of dollars in bribes to Middle East oil chiefs. Roger Walker reports. “An exposé published by the online newspaper Huffington Post and Australia's Fairfax Media said there was clear evidence that instead of using its expertise to help multinationals win contract legitimately, the company UNAOIL had paid over huge amounts of money in bribes, sometimes with the active participation of the multinationals it was working for. There has been no comment from the company or the British authorities.”
