Max Pearson presents a collection of the week’s Witness History episodes.

We hear a first-hand account of the attack at the offices of French satirical magazine, Charlie Hebdo.

Our expert guest is Dr Chris Millington, who leads the Histories and Cultures of Conflict research group at Manchester Metropolitan University.

We also hear about Swedish diplomat Raoul Wallenberg who saved thousands of Hungarian Jews during World War Two.

Plus, the Bosphorus boat spotter tracking Russian military trucks in Turkey.

Also, the Norwegian man who invented the hotel key card in the 1970s.

Finally, we’re sparking joy with Japanese tidying expert Marie Kondo.
