BELGRADE, Serbia — Tens of thousands of opponents of Serbia's populist president, Aleksandar Vucic, rallied on Saturday in Belgrade, backing up their demand for an early parliamentary election, after nearly eight months of protests that have rattled his firm grip on power in the Balkan country.
The huge crowd chanted ''We want elections!'' as they filled the capital's central Slavija Square and several blocks around it, with many unable to reach the venue.
Tensions have soared ahead of the rally that was organized by university students, a key force behind nationwide anti-corruption demonstrations that started after a renovated rail station canopy collapsed, killing 16 people on Nov. 1.
Many blamed the concrete roof crash on rampant government corruption and negligence in state infrastructure projects, leading to recurring mass protests.
''We are here today because we cannot take it any more,'' Darko Kovacevic said. ''This has been going on for too long. We are mired in corruption."
Vucic and his right-wing Serbian Progressive Party have repeatedly refused the demand for an early vote and accused protesters of planning to spur violence on orders from abroad, which they didn't specify.
Vucic's authorities have launched a crackdown on Serbia's striking universities and other opponents, while increasing pressure on independent media as they tried to curb the demonstrations.
While numbers have shrunk in recent weeks, the massive showing for Saturday's anti-Vucic rally suggested that the resolve persists, despite relentless pressure and after nearly eight months of almost daily protests.
