A new wave of protests against the law to raise the retirement age began in Paris and several French cities on Tuesday, leading to the cancellation of a third of flights at Paris Orly airport, and the disruption of about 10% of trains across the country.

Le Figaro newspaper reported that demonstrators cut off power to the Issy-les-Molyneux area, where the France Media Group is based, which owns Radio France Internationale and France 24, as well as telecommunications companies Orange and Microsoft France.

The newspaper quoted an unnamed source as saying that a group of protesters also infiltrated the Paris Olympic venue in the Saint-Denis region, where they chanted against the pension reform law without any riots.

Trade unions in France continue to oppose the reform of the government pension system, which was adopted on March 16 and is due to come into force in early September.

French authorities expect the total number of people participating in today's demonstrations to reach 600,70, including <>,<> in Paris alone.

The protests come as the opposition in parliament proposed a bill to scrap pension reform.

The proposed bill includes an additional tax on tobacco products as a solution to compensate for the financial shortfall caused by the cancellation of pension reform.

Members of parliament are due to study the proposed bill on Thursday.

French President Emmanuel Macron signed the pension reform proposal into law on April 14 after the Constitutional Council completed its review, despite demands from trade unions to abandon the measure that sparked months of protests.

The unrest intensified when Prime Minister Elizabeth Bourne, after consulting with Macron, decided to use special constitutional powers to adopt the bill without parliamentary approval.

The law raises the retirement age from 62 to 64 by 2030, requiring at least 43 years of service to be eligible for a full pension.
