Your wrap of the world stories that broke overnight.
1. The latest killing video from Isis (Islamic State) features a blond-haired Frenchman. The man, whose eyes and hair can be seen even though he is wearing a balaclava, is one of a group of jihadis who kill five prisoners in the video. He says to expect something that will "make them forget September 11 and Paris," the Guardian reports.
2. Dozens of people have been killed in a suicide bombing at a Shia shrine in Damascus' Sayeda Zeinab district. The bombing comes as talks are being held in Geneva on Syria and the main opposition group met a UN representative.
3. US presidential hopefuls were in a frantic sprint ahead of tomorrow's Iowa caucuses. Armies of volunteers knocked on doors and manned phone banks to try to ensure turnout. Donald Trump and Ted Cruz chased evangelical voters. Trump released a video featuring himself holding a Bible. Hillary Clinton appeared at an event with former congresswoman and gun violence victim Gabby Giffords.
And Clinton's rival Bernie Sanders - helped by the pulling power of band Vampire Weekend - held a massive rally in Iowa City.
