On March 24, 1999, NATO launched Operation Allied Force, an air campaign to compel Serbian leader Slobodan Milosevic to pull his forces out of Kosovo and end the conflict that had caused a spiralling humanitarian crisis.
The bombings lasted for 78 days until Milosevic finally withdrew from the Serbian province that had been agitating for autonomy for years.
During Operation Allied Force, hundreds of civilians died and were wounded when NATO mistakenly identified refugee columns as Serbian military targets.
Twenty years later, people who witnessed the bombings spoke to Al Jazeera.
