Hulkenberg uses a nice slipstream from his Audi team-mate to jump up to sixth. Looked like a bit of a dress rehearsal for qualifying tomorrow.
Verstappen has finally hooked up a lap on the soft tyres and goes top with a 1m45.787s, while Russell is second on a 1m46.261s.
McLaren was having a look at some potential damage on Piastri's car, though the team found nothing.
Bortoleto has gone straight at Turn 10.
Verstappen aborts another push lap after running wide. Been a bit scrappy for the Red Bull driver on the soft tyre.
McLaren is asking Piastri to box to check something on the car.
Very late decision from Russell, there. He was already turning in when he decided to bail as he snatched a brake.
Russell nearly crashed on the run down to Turn 3! He was on a push lap on new soft tyres and chucks it down the escape road.
Max Verstappen has gone off at Turn 1 too.
Mercedes has a big job on this afternoon to get the car ready for FP2.
The VSC has been withdrawn.
It's championship leader Kimi Antonelli who has stopped on track!
"I've lot hydraulics".
The Virtual Safety car has been deployed for an incident on track at Turn 7.
Here's a look at the Sainz brake fire.
Lots of work going on in the Williams garage on Sainz's car after that brake fire.
Williams has a big upgrade package in Baku, which it really needs to be getting mileage on.

"Something is really wrong; the engine is broken."
More issues for Hadjar.

I was mid-update when that Williams fire happened. So, I'll go back to what I was saying:
Audi will be one to watch this weekend as it has unleashed arguably the biggest upgrade package of any team all season.
Bortoleto has already been out with an aero rake fitted to his car.
Not a good start to Williams' morning. Carlos Sainz' right rear brake is on fire in pitlane!
The team looks to have gotten that under control, but that's less than ideal.
Verstappen has improved again to a 1m46.512s.
