Hello. Today we're in a hotel in Athens that's been turned into a squat, an anarchist refugee squat to be exact and home to some of the many migrants trapped in Greece.

In Bolivia we visit a multi-million pound museum celebrating the country's president, located

in a tiny and poor village few outsiders ever visit.

And another presidential tour in the US and George Washington's estate to see what he learned from the British. While in Afghanistan it's the

attack on the school in February, it's been a struggle for journalists and for the

Aside from the soft chirping of birds, in the wide trees that shade its empty classrooms,
