Former US President Barack Obama on Saturday accompanied King Felipe VI of Spain on a private tour of the Reina Sofia modern art museum in the Spanish capital, where the pair admired masterpieces from the likes of Pablo Picasso and Salvador Dali.

Obama and King Felipe spent time admiring Picasso's 1937 work of art "Guernica", which depicts the aftermath of the bombing of the town of Guernica in Spain's Basque region carried out by Italian and Nazi German planes on the petition of Spanish nationalist forces during the Civil War (1936-39).
