Nigeria's military has massacred hundreds of Shiite Muslim civilians - human rights workers say possibly as many as a thousand - in the northern city of Zaria in attacks taking place over three days.  This was precipitated by a massive protest by the Shiite group "Islamic Movement" which was demanding the release of its leader from military custody.  The army claims hundred were preventing a general's car from moving while other stalked it with petrol bomb, and gunshots rang out from the direction of the group's mosque.  Islamic Movement is opposed to Boko Haram, which has pledged allegiance to the Sunni Muslim terrorist group Islamic State.

America's second largest school district in Los Angeles shut down on Tuesday after receiving threats over email.  The move left hundreds of thousands of families scrambling for daycare, or to pick up children who had already been deposited at schools throughout the sprawling southern California city.  "The email was very specific to LA Unified school district campuses and it included all of them," said LAPD Chief Charlie Beck.  "The implied threat was explosive devices. The specific threat was attack with assault rifles and machine pistols."  All Los Angeles public shcools will be searched by the end of the day.  New York City also got similar threats via email from the same IP address, but decided they were not credible because the wording suggested the sender had no familiarity with the NY school system. 

The UK's first official astronaut Tim Peake has arrived at the International Space Station (ISS) via Russian Soyuz space capsule.  Peake, cosmonaut Yuri Malenchenko, and NASA astronaut Tim Kopra will join four other crewmembers aboard the ISS.  The docking didn't go entirely as planned, and Mr. Malachenko had to steer the craft to dock with the orbiting spacecraft due to complications with the usual automatic docking procedure.  Other Britons who have flown into space have done so either as private individuals, or took American citizenship.

France arrested a man reportedly linked to the 13 November terrorist attacks.  The 29-year old was reportedly planning to travel to Syria.  Cops took two more men into custody for allegedly selling weapons to Amedy Coulibaly, the gunman who killed four people at a kosher supermarket in January before he was shot dead by police.

Brzalian police raided the official residence of the speaker of the lower house of Congress, Eduard Cunha, as well as his home in Rio de Janeiro.  They searched for evidence in connection with a corruption scandal at the state-oil giant Petrobras.  Critics say Cunha has sought to divert attention from the corruption case against him by bringing impeachment charges against President Dilma Rousseff, claiming she broke the law in managing last year's budget. 

Argentina is gearing up for a fight over new conservative President Mouricio Macri's plans to scrap a key media law.  It was passed in 2009 limiting the number of broadcast licenses a single entity can own, and already stood up to a supreme court challenge from the country's largest media company Clarin.  At the time, justices ruled that the law was "legitimate because it favors freedom of speech by limiting market concentration".
