In Iraq, a national lockdown to halt the COVID-19 coronavirus pandemic has found some unexpected fans: local businesses who no longer have to compete with Turkish, Iranian or Chinese imports. Those countries, as well as Saudi Arabia, Jordan and Kuwait, typically flood Iraqi markets with inexpensive products at prices local producers can't compete with. (Photo by Hussein Faleh/AFP Photo)

A couple hugs while standing near a Christmas tree made out of plastic bins and plastic hampers outside the Museum of History in Monterrey, Mexico, December 4, 2015. The humble Christmas tree has a rich history, from evergreen trees used to symbolise eternal life in Ancient Egypt to tree worship among pagan Europeans. The modern version has its origins in Germany, where the song “O Tannenbaum” is still a festive favourite. Today the traditional tree with lights and decorations appears in cities including Washington, Moscow and Beirut. Alternative constructions range from recycled rubbish in Mexico City to old window frames in Rakvere, Estonia. Whatever the shape or size, the message is the same: Merry Christmas.
