oh sorry I'm also Basque (from the French side). and the second picture are guys from ETA (a terrorist organisation, they killed nearly one thousand civilians between 1970-2000)
Picture 1 is Mr Urkullu, our current official and recognized president of the Basques and of the Basque gouvernment (known as Lehendakari meaning "president" or "leader")
Picture 2 are terrorist members of ETA (you can consider it as the Basque IRA, way more violent and dangerous, anyway since 3 years they finally declared a permanent ceasefire)
