A piece of riveted sheet metal that looked like it might be part of an airplane has been discounted as potential debris from missing Malaysian Airlines Flight MH370.  The object was found near Augusta, WA and thoroughly examined.  MH370 and the 239 people on board remain missing without a trace – although officials seem convinced that analysis of radar and satellite data shows the plane went down in the Indian Ocean somewhere west of Australia.

At least four people died when a bomb detonated outside a police station in Nairobi, Kenya.  Two of the dead were police officers who had stopped the car and were questioning the occupants.  This happened near an enclave of ethnic Somalis, where Kenyan authorities have recently cracked down in search of terrorists.

South Sudan has sacked its army chief after a series of military setbacks including the loss of the oil-producing hub of Bentiu to the rebels.  The bodies of hundreds of civilians have been found in Bentiu (Warning: graphic video) after the fighting – the rebels blame retreating government forces, but reports from the area say the rebels slaughtered people from rival ethnic groups, and even killed people of its own ethnic group if they failed to support the massacre.

UN Secretary General Ban Ki-mon is blaming both sides for blocking much-needed aid from getting through to hard-to-reach areas of Syria.  Ban is urging the Security Council to pass a resolution demanding aid workers be granted greater access.  Some 3.5 Million civilians are being denied vital food, medicine, and medical care because of forces loyal to President Bashar al-Assad and rebel factions, which include western-backed units and al Qaeda offshoots.

Brazil is tightening security around World Cup venues after yesterday’s deadly riot in the favela overlooking the famed Copacabana and Ipanema beaches spilled over into the tourists attractions.  Residents were livid over the police killing of Douglas Rafael da Silva Pereira, a professional dancer on TV shows who came to the Pavao Pavaozinho slum to visit his daughter.  And a 27-year old man was killed in the ensuing riot.  It’s another blow to Brazil’s image just 50 days before the first match of the World Cup.

A US Army sergeant faces life in prison if convicted of the murders of two unarmed Iraqi boys during the US occupation in March 2007.  One boy was shot in the back, and the other was shot in the chest as he raised his hands.  Their cousin was killed when he ran to the scene – no charges filed in that killing.  Sgt. Michael Barbera’s lawyer criticized the military for filing charges years after the shootings. 

The New York City Police Department’s attempt at a community outreach on social media has failed miserably.  The NYPD encouraged people to get on Twitter and tweet their favorite photos of New York cops.  Instead of the feel-good pics of smiling faces of cops, thousands and thousands of people tweeted photos of police violence, including: Senior officers hitting and abusing women at the Occupy Wall Street protests a few years ago, and spraying others in the face with pepper spray; the aftermath of the beating of a octogenarian man who jaywalked; cops kneeling on the back of a man who later died in police custody.  Check it out on Twitter, hashtag #myNYPD.
