“Deadlines keep passing and innocent people keep dying. The log-rolling and delay has to end... This is an outrage and an insult to the people of South Sudan. Their leaders are letting them down again and again.”

“We have a responsibility to take this to the United Nations and to the world, so that all countries involved take measures ahead of time to prevent the return of these fighters and the chaos and havoc that come with that.”

An Argentinean officer, accused of committing crimes against humanity during the country’s bloody “Dirty War”, has been extradited from Bolivia.

68-year old Jorge Horacio Paez Senestrari, who had been on the run since 2011, was detained on Friday in the Bolivian city of Santa Cruz.

He is accused of aggravated homicide, during military rule in Argentina, where he served as a captain in Argentina's north-western San Juan province.

US Secretary of State John Kerry urged Myanmar’s leaders on Sunday to continue with their programme of democratic reforms, amidst local criticism that he was “too soft” on the administration, led by former military leader Thein Sein.

Concerns regarding media freedom and constitutional reforms remain in the country, which had been under military rule for decades, before the recent moves to democratise the state and the resulting thawing in relations between the west and Myanmar.

“Is everything hunky-dory? No, not yet. Absolutely not,” Mr. Kerry said. “There are still things that need to be done.”

“Next year’s election will absolutely be a benchmark moment for the whole world to be able to assess the direction that Burma is moving in.”

While Myanmar’s state media praised Mr Kerry’s visit, privately owned media, which have only been able to operate freely since 2012, criticised the Secretary of State, reported the New York Times.

The US Secretary of Defense Chuck Hagel said in New Delhi, neither India nor the US need to choose between their own relationship and closer ties with “fellow trustee” China.

Mr Hagel said in a speech to the Observer Research Foundation in the Indian capital that the US has a "unique relationship" with India, and that both countries must seize opportunities to work together on defence issues, including jointly developing and producing arms.

“Just as America need not choose between its Asian alliances and a constructive relationship with China, India need not choose between closer partnership with America and improved ties with China. In our relations with Beijing, both Delhi and Washington seek to manage competition, but avoid the traps of rivalry,” the secretary said.

“We will continue to seek a stable and peaceful order in which China is a fellow trustee, working cooperatively with both our nations.”

Mr Hagel said that the US “strongly supports” India’s growing global influence and military capabilities and the two countries have “shared interests in maritime security across the region, including at the global crossroads of the South China Sea.”

“Thousands of Afghans have been killed or injured by US forces since the invasion, but the victims and their families have little chance of redress. The US military justice system almost always fails to hold its soldiers accountable for unlawful killings and other abuses.”

“None of the cases that we looked into – involving more than 140 civilian deaths – were prosecuted by the US military. Evidence of possible war crimes and unlawful killings has seemingly been ignored.”
