A new anti-LGBTQ+ law banning Pride events and allowing authorities to use facial recognition software to identify those attending the festivities was passed in Hungary on Tuesday, leading to a large demonstration on the streets of Budapest.

A new law pushed through parliament bans pride events, the latest in a series of steps that removes rights for LGBTQ+ people. Opposition lawmakers set off smoke bombs in the chamber to protest the move.

Hungary's ruling party submitted a bill to parliament on Monday that would ban the Pride march by LGBTQ+ communities and impose fines on organisers and people attending the event which Budapest has held for three decades.
