A US drone strike last week killed an al Shabaab leader who was thought to be responsible for the 2013 attack on a Nairobi shopping mall killing 67 people, announced the Pentagon on Wednesday.

In a statement, the Pentagon said,

“He posed a major threat to the region and the international community and was connected to the West Gate Mall attack in Nairobi, Kenya. His death has dealt another significant blow to the al Shabaab terrorist organisation in Somalia.”

Almost all of the Central African Republic’s 436 mosques have been destroyed said the US ambassador to the United Nations Samantha Power, after her visit to the country last week.

Describing the scenes she saw as “kind of crazy, chilling,” Ms Power told the UN Security Council that 417 of 436 mosques in the Central African Republic had been destroyed after months of sectarian violence in December 2013.

The bombing of Raqqa by Syrian government forces may constitute war crimes, said Amnesty International, stating multiple air raids appear to have killed dozens of civilians.

Amongst the targets hit were a mosque, a school and a market, said the human rights organisation, in a report that examined air raids carried out on Raqqa in November last year. Raqqa is currently the stronghold of Islamic State militants, which has increased its hold over the city since May 2013.

“The conclusions are damning,” said Amnesty International. “In some cases, the evidence points to the Syrian government forces having violated international humanitarian law by directing attacks against civilians.”

A man from New Zealand and two Burmese men have been handed a prison sentence by a court in Myanmar for “insulting Buddhism”, after they posted a flyer on their Facebook page advertising for their bar, showing Buddha with his eyes shut, wearing large headphones.

Ye Lwin, judge at the Bahan Township courthouse, said that though the men had apoligised, they had "intentionally plotted to insult religious belief" when posting the flyer on social media.

Human Rights Watch Deputy Asia Director Phil Robertson criticised the verdict saying "by using the Religion Act to criminalise these three individuals, rather than accepting an apology and dealing with it in another way, the government is, sort of, setting up more witch hunts against persons that these Buddhist groups view as being insulting to their religion”.

"What this shows is freedom of expression is under greater threat than ever in Burma (Myanmar) just as the country heads into a pivotal election year," added Mr Robertson.

Northern Mali’s rebels agreed to another round of talks with the government after the rebel coalition said it was not ready to sign a preliminary UN brokered deal, alleging that it fully meet the demands of greater autonomy for the rebel controlled areas.

“We agreed that there should be another meeting with mediators and the Mali government.”

China has increased the amount of weapons it exports to foreign countries to become the third biggest exporter of arms, according to a report by the Stockholm International Peace Research Institute (SIPRI).

China overtook Germany, France and the UK as it increased exports of arms by 143% from 2010-14,  compared to 2005-09.

The German Chancellor Angela Merkel called on Europe to maintain pressure on Russia through sanctions, on Monday.

Speaking after a meeting with the Ukrainian President Petro Poroshenko, Ms Merkel said that a full cease-fire had not been observed and that pro-Russian militants continued to block international monitors from having complete access to the regions they controlled.

Urging the EU to agree to a “political commitment that sanctions and implementation of Minsk are closely connected, Ms Merkel added,

“The sanctions and the implementation of the Minsk plan must be connected.”
