Paris: Novak Djokovic and other players at the French Open say they are not worried about competing at Wimbledon next month despite the recent terrorist attacks in Britain.

Djokovic, a three-time champion at Wimbledon, said Sunday that he still plans on going to the tournament in London.

"I didn't get to that thought of: 'Oh, should I go? Should I not go to London with myself, my family?' Because it can happen anywhere. I mean, if it happens in London, happens in Paris, Nice, it can really happen anywhere," Djokovic said.

"I mean, if we live in fear, you know, that's not life ... If it's a destiny for you to be somewhere in some place in a wrong time, I mean, it can happen to all of us, God forbid."

Britain suffered its third major attack in three months when men using a van and knives killed seven people in the area surrounding London Bridge and Borough Market on Saturday night.

"When I heard about it today, obviously I was [as] upset as everyone," he added.

"It's very disturbing that one of the biggest cities in the world, most important cities in the world, some of the most popular locations in the town, suffering these terrorist attacks."

There was a similar attack on Westminster Bridge in London, in March, that left five people dead.

On May 22, a suicide bomber killed 22 people and injured dozens at an Ariana Grande concert in Manchester.

"I'm sure Wimbledon's on top of that stuff," said Britain's Jamie Murray, the brother of world No.1 Andy Murray.

"That seems to be the world that we have to live in these days, which is not much fun for anyone. But I guess you just have to trust in the authorities and the people that are in charge that they know what they're doing."

Rafael Nadal, who has won two Wimbledon titles and is seeking a 10th at the French Open, said: "With these kind of things, you cannot feel 100 per cent safe.

"It's tough to accept these kind of things, but it's happening very often today and [it] is difficult to change that for the moment."

France is still under a state of emergency after a string of Islamic extremist attacks, including two in Paris.

The French Open continues until next weekend and Wimbledon starts July 3 at the All England Club in London's south-west.

"It's obviously very awful what's happening, or what's happened the last few weeks, and obviously what happened here in the past, as well," said former world No.1 Caroline Wozniacki.

Nadal and Djokovic were speaking after they progressed to the quarter-finals of the French Open.

Nadal hammered compatriot Roberto Bautista Agut 6-1, 6-2, 6-2 in a fourth round performance that was also an emphatic statement. Nadal has not lost a set so far this tournament, and is on track to win the title without doing so, something he did in 2008 and 2010. Only Bjorn Borg (1978 and 1980) and Ilie Nastase (1973) have also achieved that feat.

His countryman Carreno Busta, who has enjoyed a meteoric rise in the last 18 months, going from a ranking of 67 at the start of 2016 to world No.21, sent Canadian world No.6 Milos Raonic packing in five sets.

Carreno Busta, underpowered against Raonic, ground out the win 4-6, 7-6 (7-2), 6-7 (8-6), 6-4, 8-6 as 84 unforced errors spewed from the Canadian's racquet. The win was Carreno Busta's first over a top-10 player.

Defending champion Djokovic got past another Spaniard in Albert Ramos-Vinolas, outclassing him 7-6 (7-5), 6-1, 6-3, and will face rising Austrian star Dominic Thiem in a rematch of their 2016 semi-final.

"Now it is the quarters in a grand slam and facing Dominic is not easy. He is a one of the best players in the world, especially on this surface," Djokovic said.

Thiem advanced to the quarters with an easy 6-1, 6-3, 6-1 win over Argentine world No.65 Horacio Zeballos.
