Impressive footage of a game of tennis played from the rooftops under Italy's strict coronavirus lockdown has prompted a massive response on social media.

The video shows two young women in the Liguria region of Italy exchanging shots in a continuous rally that lasts 22 seconds.

It was posted to Twitter on Saturday by the official ATP Tour account. At the time of writing, around 20 hours later, it had been viewed 3.8 million times.

Its caption was "Just incredible to see", accompanied by a heart emoji and the hashtag #tennisathome.

The video was also published by Italy's Corriere Della Sera newspaper, which noted that the reactions were mostly admiration for the players, with a few people wondering what would happen to the balls if they missed a shot.

Italy is one of the countries hit hardest by the coronavirus. Its death toll — more than 23,000 — is second only to the US.

It has been under a strict nationwide lockdown since March 10, and the government has said most restrictions will remain until at least May 3.

Some limited exceptions have been introduced to allow some stores — including book stores — to re-open, and some other industries to restart. A full list was published earlier this week in English by The Local.it.
