Formula One team principals have explained how they were reassured of their safety in extensive talks following a missile attack near the Saudi Arabian Grand Prix.

The attack on an oil depot prompted an explosion that delayed FP2 in Jeddah on Friday.

F1 confirmed later on Friday and again early on Saturday the race would be going ahead, having met with the teams and heard their concerns before Saudi government authorities and security agencies offered "full and detailed assurances that the event is secure".

Facing the media ahead of FP3, team principals elaborated on these discussions, with Haas chief Gunther Steiner revealing: "For me, the assurance is if the authorities have got their own families here and they feel safe, I can be safe as well.

"They explained very credibly what [system] is in place. The technical details I am not in a position to explain that, because I'm not qualified enough. But there is stuff in place, which protects us, obviously. I'm not trained in that one.

"The credible explanation of what they do, and that their families are here with them, that gives me the assurance that I'm safe and that my team is safe."

Aston Martin's Mike Krack added: "We had quite a few high ranked authorities yesterday, and they explained to us the situation, they explained it to us in a very credible way.

"This made all of the 10 of us that were in the room confident that they take their responsibility very seriously."

Andreas Seidl of McLaren said: "In the end, we need to trust F1, and the authorities here, put safety always first for every single member of the paddock here.

"I have full trust that this is happening."
