Kittel caught out and dropped by peloton
GB's Froome retains yellow but Ireland's Martin loses time
Another frenetic day on the Tour de France comes to a close.
You can read all about it in our report, which is building here.
The yellow jersey competition is still in the balance, as is the green jersey battle after Michael Matthews' victory today.
Join us tomorrow for stage 17.
But for now, goodbye.
Here's Michael Matthews taking the win, his bike lunge enough to hold off Edvald Boasson Hagen.

Ireland's Dan Martin, speaking to ITV4: "I didn't have great legs today and the team was suffering.
"We put a brave face on it at the start but we've had a few people sick.
"The climb put everyone in the red and then it was so dangerous on the downhill. I had to slam the brakes on a couple of times and that contributed me to losing a few places."
Stage winner Michael Matthews: "Normally I can win one stage in a tour but the second one hardest to get.
"To get two in three days won't sink in until tomorrow morning.
"I was trying to go in the breakaway but Quick-Step covered me then I heard Marcel Kittel was getting dropped so I put the pressure on.
"When he was one minute over the top of that climb we decided to start really pulling and give me a better opportunity to go for the sprint at the end."
No changes in the top four, who are all within 30 seconds, but Dan Martin the big loser as he slips out of the top five.
Alberto Contador also slips out of the top 10 and Louis Meintjes loses yet more time to Simon Yates in the best young rider's competition.
The race jury have had a look at the flick from Matthews that Degenkolb was complaining about.
Nothing doing - Matthews remains as the stage winner.
Mikel Landa and Simon Yates do indeed leapfrog Dan Martin into fifth and sixth respectively.
Chris Froome retains the yellow jersey, he was well-protected by his Sky team-mates all day.
Looks like Dan Martin has lost 51 seconds after being caught out by that split in the run-in, which drops him down to seventh overall on general classification.
From side on, it wasn't as close as first thought - Matthews had about a wheel on Boasson Hagen, who came from miles back but ultimately left it too late.
Degenkolb was gesticulating wildly that he'd been blocked off by Matthews in the finale.
Just frustration or could there be more to Degenkolb's protest?
A perfect day for Michael Matthews ends in the perfect result.
His second stage win of this Tour.
The Aussie's Sunweb team were majestic today - dropping green jersey Marcel Kittel on the first climb, never to get back on.
He won the intermediate sprint and then takes maximum points in Romans-sur-Isere - 50 points overall.
He trails Kittel by just 29 points in the points classification now.
Degenkolb, Matthews and Boasson Hagen all there on the line.
It's too close to call...
Greg van Avermaet goes early - where's Edvald Boasson Hagen?
Has he left it too late - here comes the Norwegian...
Michael Matthews there too...
Bennati is about to be caught as he passes under the 1km to go mark.
Sprint to come...
2km to go
Movistar's Daniele Bennati tries to catch out the front group with a long-distance dig.
Sunweb's Warren Barguil leaps to the front to close it down, in service of team-mate Michael Matthews.
Here's who to look out for in the finish - Michael Matthews, Edvald Boasson Hagen and John Degenkolb are all up there.
Greg van Avermaet may also fancy a long-distance surge.
Boasson Hagent the favourite now, for me.

Dan Martin's podium hopes are on the line now.
Jack Bauer has gone very deep into the red, trying to bring back the front group for his team-mate Dan Martin.
He finally swings off, exhausted and no one comes through to take it on.
Alberto Contador has also slipped almost a minute behind the front group now.
It wasn't Mikel Landa who was the Sky rider going out the back, the Spaniard is still up there with his leader Chris Froome.
Into the final, frenetic five kilometres we go.
