Roger Federer and Novak Djokovic have joined the chorus of other athletes to mourn and support France following a series of terrorist attacks in Paris that led to the death of hundreds of innocent people.

Federer and Djokovic are among the players at the Barclays ATP World Tour Finals in London to pay tribute to the victims of the Paris attacks over the weekend. In the opening round of the season finale tournament, all the players wore black ribbons on their shirts as a mark of respect to the victims of deadly attacks in Paris.

"I just would like to reflect on what happened a couple of days ago [in Paris]," Djokovic said, reports ESPN. "All my heart goes to the families of the lost ones, it was really devastating to see those images and footages.”

Federer won his first match at the Barclays ATP World Tour Finals against Tomas Berdych 6-4 6-2, while Djokovic only needed 65 minutes to trash Kei Nishikori of Japan 6-1 6-1, extending his latest winning streak to 23 matches.

The ATP World Tour’s official website has released a statement about tightened security in light of Paris’ tragic incident. The statement said the security options in placed around the event in London have been reviewed and the venue will be monitored at all times to ensure the safety of all visitors and players.

“Our deepest condolences are with all those affected by the tragic events in Paris,” the statement added. “Following the events overnight, we have reviewed security operations in place around this year’s Barclays ATP World Tour Finals.”

Meanwhile, Federer, the favourite to win this year-end tournament, is set for a massive showdown against Djokovic in the second round of Stan Smith Group matches on Tuesday.
