"Fernando Alonso is on the intermediate tyre on a dry track and the reason for that is because McLaren have discovered a cut on the last set of prime tyres he was using, so they don't want to risk going out on the prime tyre until they know why that cut appeared."

Into the final 20 minutes of the session and there's once again a lull on the track. Just Carlos Sainz, Pastor Maldonado and Fernando Alonso out there. Alonso, interestingly, is on the intermediate tyre...

"What we are seeing down with Mercedes and Nico Rosberg reminds me of something. Rob Smedley said to me on Thursday about just how unprepared teams feel coming into this race. The tarmac was laid very late so there is very little data about it. The top speed at the end of the pit straight is much higher than the teams were expecting. It will be a moving target and when they put the soft tyre on it will go faster again. A lot for the teams to think about."

After that fiery drama, we have a Red Bull one-two at the moment with Daniil Kvyat fastest after a 1:26.295 ahead of Daniel Ricciardo. Nico Rosberg is third fastest.

"Cool these brakes down Lewis," Hamilton is told over the radio. "They are too hot. Keep cooling the brakes."

Sage advice after what just happened to his team-mate!

Yellow flags as Nico Rosberg, who has the fastest time of the session, brings his car to a screeching stop as he goes off the circuit, and just stops himself from hitting a barrier. He rights his car but his brakes are on fire! Replays show him limping the Mercedes back to the pits with fire inside his rear tyres!

A brief flutter of the yellow flags as Felipe Nasr spins at the last corner inside the stadium section. He manages to avoid contact with nearby barriers and rights himself before getting back on his way.

"I've just gone next door to Jenson Button and Nico Hulkenberg is out of the car. It appears the team are working on the steering rack. It appears to be quite a big job but let us hope he can get back out soon."

"Jenson Button is out of the car having reported a power issue. It might be an early bath for Jenson, who was given a new power unit but it appears to have let him down already."

Jolyon Palmer, for the briefest of moments, was fastest of all after a 1:29.163 before Nico Rosberg knocked him off top spot with 1:28.399. Replays, though, did show Palmer cutting off a bit of Turn 10 when he ran wide. 

All 20 drivers have put times on the board, with Jolyon Palmer and Nico Hulkenberg the last two to do so. 

Hulkenberg, though, is back in his garage at the moment as Force India take a look at a brake problem in his car.

Plenty of drivers are still in their respective garages with some tinkering being done to their cars. Daniel Ricciardo is out on track, and he becomes the first of the drivers to dip below 1:30 today as he goes fastest with 1:29.502, just over a second faster than Valtteri Bottas.
