Mexican police have arrested a gang leader believed to be the key figure in the disappearance and likely murders of 43 student teachers in southern Guerrero State near Igaula town nearly a year ago.  Prosecutors allege that 36-year old Gildardo "El Gil" Lopez Astudillo gave the order to kill the 43, whose disappearances shocked a nation that had appeared to have been become numb to drug gang violence.  The case has proved to be an albatross around the neck of President Enrique Pena Nieto, who took office in 2012 promising to stamp out drug-related violence.

Croatia has closed all but one of its border crossings with Serbia, unable to cope with the more than 10,000 Middle Eastern and other refugees who crossed over from Serbia in just one day.  They were taking the long way around after Hungary blocked its border with Serbia with razor wire, cutting off the land route to Northern Europe where the refugees hope to find more favorable conditions for asylum.  But at least some of the trekkers are getting the last laugh on Hungary's xenophobic actions - Hungarian media says they were able to cross into Hungary from Croatia at Illocska, thus avoiding the razor-wire fence.

Greece will hold its third election of the year this weekend.  Two polls show the governing Syriza Party losing its steam, no longer trusted by the Left Wing after it betrayed its stated ideal of fighting EU-imposed austerity.  Syriza is neck and neck with the center right New Democracy Party, with the disgusting nazi scum Golden Dawn party in third.  No matter which wins, the country's economic policy is being written in Brussels, so.. good luck with that.

Pope Francis arrives in Cuba on Saturday for a nine-day visit in that country and the United States.  Some are angry that the Pontiff isn't planning to meet with Cuban political dissidents, but then he didn't come into the job with the same strong anti-Communist drive that his two immediate predecessors had.  But he has made waves with his strong anti-capitalist message, and there are concerns about what the leader of the world's Roman Catholics will say to the leaders of the world's richest nation about the accumulation of wealth by its top one percent.

The Pakistani Taliban took responsibility for an armed attack on air base near Peshawar.  The email claimed it was a suicide squad carrying out the attack.  Six of them died, and the other four apparently were slacking off.  The has been much quicker to respond to Taliban strikes after last year's attack on an army-run school in which 150 students and teachers were killed.
