A crowd of angry mourners chased Serbian Prime Minister Aleksandar Vucic during a ceremony for the 20th anniversary of the mass killing of Muslims in Srebrenica on Saturday, pelting the Serbian leader with rocks and bottles.
The prime minster was reportedly hit in the face with a stone, breaking his glasses.
A large group booed and chased Vuvic up a hill at the memorial site, with the prime minister and his delegation running towards their cars.
