Demonstrators stormed the building of the Mexican Senate on Tuesday and interrupted debates on judicial reform, Reuters reported, quoted by BTA.
This added drama to the already tense debate over the reform, which critics say could undermine the rule of law in Mexico.
Senate President Jose Gerardo Fernandez declared the session adjourned and urged lawmakers to remain calm as demonstrators chanted "traitors" in the building of the upper house of the Mexican Parliament.
There have been protests against the reform for several weeks now, notes Reuters.
Mexico's main trading partners, the US and Canada, have warned that the changes would adversely affect the trade agreement between the three countries and investment.
The essence of the constitutional reform proposed by President Andrés Manuel López Obrador is the idea that more than 6,500 judges and magistrates, including members of the Supreme Court, should be elected by the people.
López Obrador and Mexican President-elect Claudia Sheinbaum are advocates of the reform, which they say will ensure greater transparency in the work of judges and reduce corruption.
