The banker and his Picasso, turtles in trouble and more

 French customs officers have seized a Picasso painting from a yacht docked in Corsica and returned it to Spain where authorities describe it as a "national treasure."  Banker Jaime Botín has been keeping the 1906 painting on his yacht, hoping to find a way around the Spanish ban against its export and sell the work.  The painting is now being held in storage at Madrid's Reina Sofia Museum until the legal dispute is resolved.  The turtles at the Atocha train station are suffering overcrowding.  And finally, on a more serious note, another view of the historic nuclear accord with Iran.
