That's four gone.

One of the BBC F1 team is very distraught at Kimi Raikkonen's retirement. That opening lap damage with a shunt with Daniel Ricciardo could just not be fixed and for the third time this season Raikkonen's race ends early.

Kimi Raikkonen is in the pits again... they're not doing anything with the car.

It looked they were just looking at the rear wing, maybe he was having problems with DRS. There was a lot of head scratching and some man handling of it.

Kimi Raikkonen is back in the pits for a second time. He is down in 16th. Remember in Q2 he broke the lap record, but in Q3 he was left stranded in the garage as the track dried off.

That left him down in sixth place, but a first-lap tangling with Daniel Ricciardo caused him an early puncture, and now he has to fix even more damage to his Ferrari.

Furious moment for Alonso, but it wasn't his fault. It was Hulkenberg behind him. It is infuriating for Alonso, he will be going back and looking at the replays as an innocent party...

Leclerc is out, Alonso out, Hulkenberg out.

Charles Leclerc is just walking past and I asked if he was OK and he smiled as if to say 'I don't know' then he waved at the crowd and they clapped for him. A really horrible moment there with a car going over the top of his head. He will be looking closely at the replays for that.

Brilliant move from Max Verstappen, to the delight of the home fans. He leaves it late, feigns right and goes left just nabbing Esteban Ocon at the corner. Great move. Verstappen fourth, Ocon's team-mate Sergio Perez is next up for the Belgian-born Red Bull man.

Sebastian Vettel with a 2.2 second lead. Lewis Hamilton is on the hunt to regain the lead that he lost on lap one.

F1 is a tough, tough game. Charles Leclerc trudges back to the pits after his race was ended when Alonso flew over him.

But Leclerc should just thank his lucky stars that he has got away from that one unscathed. That could have been an absolute disaster.

What a chance for some lesser teams to grab some points. Raikkonen down in 15th, Ricciardo 17th and a lap down.

That little lock up might have cost Hamilton what he needed to overtake Vettel after the safety car restart.

A word on Force India. Sergio Perez and Esteban Ocon have switched their opening positions, with Perez now third.

Jeremiah Kariuki: Hamilton will be furious at the Racing Control for not calling the Safety Car fast enough. Let us expect some grumpy radio calls! #BBCF1 #BelgiumGP

Jamie Dunn: And as always, I’m cheering for the guys in pink - come on @ForceIndiaF1, external! #BelgianGP#BBCF1

Jacqui Baker-Stubbs: Is it just me, or does @alo_oficial, external have the best crashes of anyone on the grid?! Gets airborne and still manages to walk away. At least he didn’t roll this time like Turn 3 at @ausgrandprix, external a few years ago #BBCF1, external#BelgianGP, external

Hamilton attacks Sebastian Vettel straight after the restart, it looks like the Briton has got him, but Vettel just about hangs on.

Five laps gone (most under the safety car), three drivers out, two more in trouble, what a race!

Safety car is ending. We go again.

It seems that Kimi Raikkonen's puncture was caused by Daniel Ricciardo. Both seem able to carry on, with the Australian two laps down after some frantic repairs from Red Bull.

Fernando Alonso has been involved in a massive smash here before. At exactly the same corner - La Source.

Romain Grosjean landed on top of the Spaniard, in a way similar to how Alonso just went over Charles Leclerc today.

We are still under the safety car by the way.

Some front wing damage for Valtteri Bottas as well.
