This winter is going to be a warm one for the majority of the United States, according to forecasters at NOAA's Climate Prediction Center.

Taliban militants wiped out almost an entire Afghan Army base in Afghanistan's Kandahar province, leaving just two Afghan soldiers there uninjured. This brings the week's toll to more than 120 people killed by the militant group.

The schools in Puerto Rico are facing massive challenges.

All the public schools are without electricity, and more than half don't have water. More than 100 are still functioning as shelters.

But Puerto Rico's secretary of education, Julia Keleher, tells us that the schools that are open are serving as connection points for communities. They've become a place where children and their families can eat a hot meal and get some emotional support, too.

The only known Leonardo da Vinci painting in private hands is heading to auction.

The portrait of Jesus Christ, Salvator Mundi, was only recently confirmed to be by Leonardo. This piece was thought to be a copy of a destroyed original. And it's still not clear where the painting was, exactly, for more than a century.

Back-to-school season didn't last long this year in Puerto Rico. First Hurricane Irma and then Maria forced schools to close and turned the lives of students and their families upside down.
