BELGRADE, March 4 (Reuters) - Serbian opposition lawmakers threw smoke grenades and tear gas inside parliament on Tuesday to protest against the government and support demonstrating students, with one legislator suffering a stroke during the chaos.
Four months of student-led demonstrations have drawn in teachers, farmers and others to become the biggest threat yet to President Aleksandar Vucic's decade-long rule, with many Serbians denouncing corruption and incompetence in government.
