Thousands have marched in Marseille, France, to denounce drug trafficking after the killing of an activist's brother sent shockwaves across the country. Mehdi Kessaci, 20, was killed last week in a shooting officials believe was ordered by drug criminals to intimidate or punish his older brother, Amine, a prominent anti-drugs campaigner.
An estimated 6,000 people, many dressed in white, gathered behind a 'Justice for Mehdi' banner. They observed a minute of silence and raised hands in rejection of drug violence, with politicians from across the political spectrum also joining the demonstration.
