The International Criminal Tribunal for Rwanda (ICTR) held its final hearing on Wednesday, concluding more than 20 years of work indicting those responsible for the 1994 genocide, which saw the deaths of more than 800,000 people.

Based in Tanzania, the ICTR has indicted 93 people throughout its history, becoming the first international tribunal to deliver verdicts in relation to genocide and the first to recognise rape as a means to carrying out genocide, reports the BBC.

As the final hearing concludes, 61 defendants have been convicted and 14 acquitted by the court. Other suspects have been tried by different courts, remain at large or have since died.

The final hearing was an appeal from former women's minister Pauline Nyiramasuhuko, who was the first woman to be found guilty of genocide by an international tribunal, when she was convicted in 2011.

The Japanese prime minister, Shinzo Abe, said Japan felt “deep remorse” at its actions during World War Two, stopping short of the apology demanded by countries affected, including China and Korea.

Newly unveiled electoral reform proposals from Hong Kong’s government continues to allow the screening of candidates for the 2017 elections by Beijing, going against the central demand of pro-democracy activists.

Hong Kong's leader Leung Chun-ying said that there was “no room for any compromise” and that “if this proposal is vetoed, it could be several years before the next opportunity.”

Putting forward the proposals, Carrie Lam, Hong Kong's chief secretary, said that they "are in strict compliance with the Basic Law [Hong Kong's constitution] and the relevant decisions of [China's] standing committee of the National People's Congress."

"At the same time they fully take into account the views expressed by various sectors of the community," said Ms Lam.

As she made the announcement, several democratic lawmakers walked out in protest. Alan Leong from the Civic Party said, "We will launch a campaign to oppose the proposal and we will ask the Hong Kong public to continue to seek true universal suffrage."

Saudi Arabia has resumed air strikes on Houthi rebels, only a few hours after announcing and end to the attacks by the coalition it leads.

The government said on Tuesday the air strikes had “achieved its goals”, and the threat to Saudi Arabia was removed.

The negotiations between Iran and the European Union recommenced on Wednesday, with the timing of the removal of sanctions proving to be a vital point in further successful negotiations.

The deputy foreign minister of Iran, Abbas Araqchi, after arriving in Vienna, said,

The US navy has sent one of its aircraft carriers to the sea off the Yemeni coast, amidst reports an Iranian naval convoy is carrying arms for Houthi rebels.

A US spokesperson said the ship would not stop the Iranian convoy, and said the deployment was to secure trade routes in the region.

The USS Theodore Roosevelt, an aircraft carrier, and a guided-missile carrier, the USS Normandy, will join other vessels in the Arabian Sea off Yemen, US officials said.

"We believe these vessels may have arms and equipment on board. If they are delivered to Yemen, it will further destabilise" the country, the official was quoted by AFP as saying.

A court in Egypt sentenced former president Mohammed Morsi to 20 years in jail on Tuesday, finding him guilty of the arrest and torture of protestors.

Mr Morsi, who was ousted by Egypt’s security forces in July 2013, was facing the first of several trials, related to the deaths of protestors in December 2012. He also stands accused of passing on intelligence to a foreign country.

 A former Nazi SS guard said he is “morally” guilty for his role at Auschwitz concentration camp, as he faced trial at a court in Germany on Tuesday.

Oscar Groening, 93 years old, referred to as the “accountant of Auschwitz”, told the court of the two years he spent at the camp, as he went on accused of being complicit in the genocide.

“It is without question that I am morally complicit in the murder of millions of Jews through my activities at Auschwitz,” said Mr Groening. “I ask for forgiveness. I share morally in the guilt but whether I am guilty under criminal law, you will have to decide.''

The German government will support a resolution later this week, describing the massacre of around 1.5mn Armenians in 1915 as a genocide, according to Chancellor Angela Merkel's spokesman Steffen Seibert.

"The government backs the draft resolution ... in which the fate of the Armenians during World War One serves as an example of the history of mass murders, ethnic cleansings, expulsions and, yes, the genocides during the 20th century," Mr Seibert said according to Reuters.

German Foreign Minister Frank-Walter Steinmeier had earlier rejected using the word genocide, in an interview with public broadcaster ARD TV on Sunday, and denied it was to avoid upsetting Turkey.
