Was very dumb of my part to not add context, so here it is :
1st clip : Halit Barani. A survivor of the mass ethnic cleansing of Kosovars (1998-1999) by the Serbs. He was a testimony against Slobodan Milosevic, Yougoslavia’s last leader, who orchestrated every Yougoslav war (90’s), one being the Bosniak genocide.
2nd clip : Same video but different moment. He was basically attesting somewhat a ceremony and giving a speech for the job he did at the Hague.
3rd clip : NATO (perhaps?) tanks entering Kosovo to fight against the Serb army (Yougoslavia came to a break after the slip of other Southern Slav countries).
4th clip : KLA militia showing a gun basically.
5th clip : Adem Jashari, a KLA commander and one who took a big part in its inception and spread, and his father, Shaban Jashari.
