Paris, France (CNN) -- Some 200 demonstrators blocked France's Marseille-Provence airport for more than three hours Thursday as strikes and protests continued across the country, trade unions said.
A large rally was scheduled for central Paris in the afternoon as demonstrators stepped up protests against a government proposal to raise the national retirement age from 60 to 62.
Pop star Lady Gaga postponed two Paris shows this weekend because of "the logistical difficulties due to the strikes," her website said.
"Unfortunately, as there is no certainty that the trucks can make it to the Bercy for this weekend's shows, the Lady Gaga performances are now postponed," the statement said.
The French Senate is working its way through roughly 1,000 amendments to the pension reform bill, and a final vote on the bill could be as early as Thursday and as late as Sunday.
The lower house of parliament has already passed it, by a vote of 329 to 233.
If there are substantial differences between the Senate and National Assembly versions, a conference committee will have to iron them out before the final version goes to the president.
