Big changes in the government – An apparent revenge motive in the murders of two New York City cops – Castro welcomes the new era, but insists Cuba will stay Communist – And more in your CareerSpot World News Briefs:

Prime Minister Tony Abbott reshuffled his cabinet.  David Johnston has been dumped from the cabinet, and former Social Services Minister Kevin Andrews is moved into defense.  Sussan Ley becomes the second woman in the Abbott cabinet with her move into health.  The PM promoted Peter Dutton from health to immigration and moved Scott Morrison from immigration to social services. 

37-year old Mersane Warria is now formally charged with the murders of seven of her children and her niece in a home in suburban Cairns on Friday.  The victims were four girls – aged 14, 12, 11, and two; and four boys – aged nine, eight, six and five.  Police are looking into the possibility of methamphetamines abuse by the suspect.

A man walked up to the passenger side of a New York City police car, pulled out a gun and opened fire – killing two cops.  Police say 28-year old Ismaaiyl Abdulah Brinsley tried to escape into the subway with other officers in pursuit, and witnesses say he committed suicide on the train platform.  His motive was apparently revenge for the police abuse and killings of unarmed black men in recent months, and he apparently posted anti-police messages to his social media account.  Earlier in the day, Brinsley shot and wounded his ex-girlfriend in Baltimore, some 315 kilometers to the southeast, before driving to New York to kill the cops.

French police shot and killed a man who produced a knife on a train platform in Joue-les-Tours, a suburb of the city of Tours in central France.  The suspect yelled “Allahu Akbar” as he wounded three officers with the knife.  French investigators are now determining if he acted alone, or was part of a broader terrorism plot.

The US released four Afghani presidents from the Guantanamo Bay prison camp and is sending them back to their home country.  The four were held with suspected terrorists for more than ten years, but were suddenly deemed to be not a threat anymore.  The Afghan government says the men will eventually be reunited with their families.

Cuban President Raul Castro gave a nationally-broadcast speech addressed to Parliament to update the situation with the US:  Raul thanked his US counterpart President Barack Obama for opening “a new chapter” in US-Cuban relations, but insisted that the US refrain from interfering in Cuban domestic affairs, and reaffirmed the Communist form of government.  Castro also confirmed he will participate in the Washington-backed Summit of the Americas in Panama in April, potentially setting up his first meeting with US President Barack Obama since the two countries agreed on Wednesday to reestablish diplomatic ties.

Russian President Vladimir Putin is accusing the West of “a complete lack of interest" in resolving the crisis in southeast Ukraine” with the new round of economic sanctions.  Putin’s spokesman says Russia is developing “retaliatory measures”.  The US, Canada, and European Union last week enacted similar orders to ban the export of goods, technology and services to Russian-occupied Crimea.
