Formula 1 has plenty to discuss after a Saudi Arabian Grand Prix weekend that raised questions about the race's continued presence on the calendar.

A missile attack on a nearby oil storage facility by Yemen's Iran-backed Houthi group last Friday cast doubt on Sunday's race, with drivers meeting for more than four hours to consider their stance as the plant burned.

The sport eventually decided collectively to carry on after receiving security assurances from Saudi authorities.

While Sunday served up a riveting floodlit spectacle around the thrilling Jeddah Corniche track, there was acknowledgement that Formula 1 needed to assess its newest fixture.

"I don't want to go too much into details on this subject now, but it's definitely a discussion that we should have after this race, once everything calms down," said Ferrari's championship leader Charles Leclerc.

British driver Lewis Hamilton criticised Saudi Arabia's human rights record before the race and later said he was looking forward to leaving the country.

Drivers also had reservations about the track, with its blind, high-speed sweeps and flat out straight stretches along the Red Sea.

Organisers made changes to improve drivers' sight lines for this year's race, after the first last December.

But a heavy crash for Mick Schumacher's Haas in qualifying underlined the perils.

Ferrari's Carlos Sainz added: "When you see an accident like Mick's [it] gives us a bit [of] tranquillity that even at those speeds the car is protecting you, because the [governing] FIA has done a great job in giving us very safe cockpits.

"But at the same time, is it really worth it?"

15-year deal for Saudi grands prix 

Saudi Arabia has signed a 15-year hosting deal with F1, with the fees contributing significantly to the bottom line for F1 owners Liberty Media.

The grand prix also reflects the Middle East's growing profile and influence within the sport, with state-owned energy giant Aramco a major F1 sponsor and joint title partner of the Aston Martin team.

British supercar makers McLaren are majority-owned by Bahrain's sovereign investment fund Mumtalakat, with Saudi Arabia's Public Investment Fund (PIF) also providing significant funding.

Sunday's event was the fifth in a row in the region which will again have four races on the calendar in 2023 when Qatar returns after hosting the soccer World Cup.

Neighbouring Bahrain played host to the official pre-season test and the season-opener on March 20.

Formula 1 argues, in the face of criticism from human rights groups, that it can act as a force for change in the region.

"Does Saudi Arabia and some of the other Middle Eastern countries share the same values and culture as we do in Europe? They don't," said Mercedes team boss Toto Wolff.
