13:51 CET -  The night session at the French Open will be brought forward by half an hour this year, tournament director Amelie Mauresmo said on Friday.

"It will start at 20:00 CET with an interactive show and the first point will be played at 20:30," she told a news conference.

Last year, players entered the Court Philippe Chatrier to warm up at 20:45 CET, and the scheduling drew criticism due to the lack of public transportation in the event of a late finish.

The Paris metro stops running around 1:15am.

Organisers were also criticised for scheduling mostly men's matches in the flagship match of the day, and Mauresmo would not commit to putting on more women's matches this year.

"It's difficult to project before the draw," she said.

8:25 CET - The International Olympic Committee's (IOC) recommendation to allow Russian and Belarusian athletes to return to international competition as neutrals is "confusing" because Ukraine is still under attack, tennis world number one Iga Swiatek (21) said.

The IOC sanctioned Russia and Belarus after Moscow launched the invasion of Ukraine in February 2022 but is now eager to see athletes come back across all sports and have a chance to qualify for the Paris 2024 Olympics.

Russia says it is prosecuting a "special military operation" in Ukraine.

Russian and Belarusian tennis players have been competing on the tours and at the other Grand Slams as neutrals since March last year.

"Right now the situation is pretty complicated because at the beginning of the war there weren't many decisions one way. At first they (Russian and Belarusian athletes) were kind of banned in other sports, not in tennis," Swiatek told reporters on Thursday.
