vladimir putin, after mr putin said he will not expel any us diplomats in response to washington's expulsion of 35 russians. writing on social media mr trump said — police in rio dejaneiro are questioning the greek ambassador‘s wife and two other people on suspicion of involvement in the envoy‘s killing. investigators say the ambassador‘s body was found in the boot of a burnt—out car. the nationwide ceasefire in syria is now over 2a hours old. while it appears to be holding in most areas — moscow says it calls on the un security council to back the deal and support new peace talks. now on bbc news, it's time for click. this week, a click christmas with digital jumpers, hatched technology and tie fighters. hello, and welcome to the annual

clickmas get together. cue christmas cheer. cheering and enough. we have everyone here, jen, steve, nick, laura, mark and kate russell. hello. i have sought out a little christmas gift for you. thank you very much. it's an egg. it is an egg. right. inside it is a hatchimal. it's the latest robotic interactive toy. it's got loads of sensors and it's for ages five and up and your child basically has to nurture the egg in order to hatch it and then it breaks its way out of the egg and then you teach at games. you care for it, basically.

you have to feed it. you're going to be a daddy. thank you very much. i shall name you...later. better put it somewhere not on the table so we don't accidentally eat it. we have had some adventures this year. we have been all over the place and click is a 52—week—a—year production, so it is difficult to get the whole team in one room. this is the kind of thing we have been doing this year. i am so luke skywalker. my bad. half a billion pixels on display here. some of the most extraordinary athletes you will see this year. say hello to the mega bot mark ii. the world's highest glass walkway. this is absolutely stunning.

this week we are going to look back at some of our best bits from 2016, and we start with a really positive story in a place that you wouldn't think there was any positivity at all. earlier in the year, jen wentjordan, to the border with syria, to look at some of the innovation happening in syrian refugee camps there. that's right. i went to zaatari, the biggest refugee camp in jordan. there are 80,000 refugees living there and it's actually a community of makers. i was fascinated to find out, and they are making some incredible technology out of some very rudimentary things in the camp. the main street here in zaatari is called champs elysee. it is a play on two things, the champs elysee in paris and cham, the word syrians refer to damascus by. there are several hundred shops lining this street and you can find everything from bridal

dresses to vegetable shops, barbershops and even quite a few mobile phone shops. technology here is being used in inventive ways to ease daily life here. the camp is a community of makers and one of the most innovative people we met is safwan harb. three years ago safwan fled the violence in syria with two family members. they all have disabilities and struggled to get around on the unpaved roads. he wanted to have more independence and designed an electric bike around spare parts he found. giving refugees access to technology and education is the focus of a group called refugee 0pen ware. one of its start—ups is focused on fabrication technology, including 3—d printing. assam was an ambulance driver in syria and lost his leg in a bomb explosion. as well as customising his own prosthetics, he helped a young yemeni boy, named zain, who lost part of his hand in a fire.

they were able to include elements of zain‘s favourite cartoon character, ben 10, in the design, all forjust 75 us dollars. assam also helped develop a 3—d printing system using haptic feedback for another syrian refugee named ahmed. he was blinded by a sniper shot that went through his eyes. the echolocation system helps guide him to walk around unaided. they are planning to open fabrication labs in a refugee camp in turkey and in the northern jordanian city of irbid. it is a small but positive step to harness the talents of people forced into exile and help integrate them into a new country. brilliant. that wasjen, and for the next part of the programme, i have had to clear the room because there is a serious danger to human life in this next item. is that not right? it is exactly right. the last few years, one

of the biggest gifts people have been getting is, of course, drones. now, for the next few christmases, a star wars movie will be released as well. as it should be. exactly. combine the two and what do you end up with? star wars drones. hums the imperial death march now, there is something special about these drones, isn't there, spencer? they are notjust drones we can fly about, we can actually engage in combat. they are armed with infrared guns, which means you can fly them about and then press the fire button. you are going to get your best anakin skywalker on, well, it would be luke skywalker because you have the x—wing and i have darth vader's tie fighter. when a shot is registered, we get a rumbling in the controller and you have got three lives there as well. feel the force. the force is strong in this one. talking of which, you met an amazing flying man this year. yeah, a man who flies like a bird.

his name is yves rossy. he has an apparentice now called vince reffet. he's based out in dubai and he is thejetman. he has built and designed this enormous jet wing that allows him to fly in excess of 100 mph at about 5,500 feet. it is really quite remarkable. we went up for a flight with him and saw what he does. jetman‘s training centre is based at this hangar in the desert outside dubai. today, i am going to watch him do hisjet—powered thing up close. how are you feeling? good. charged? yeah, yeah. ready to fly. in this hangar, yves and his team maintain thejet wings, which are capable of flying at 189 mph. so, you're not flying solo anymore? no, that is the big advantage now, is to have a friend with me in the air, vince.

vince reffet has plenty of airborne experience as a three—time world champion skydiver. as a kid i would watch the magazine and i would see what yves was doing as a pilot and as a pioneer of wing shooting and skate—surf and flying. i would see who was yves. outside the hangar, things are getting a bit noisy. so, this is why we got up early. 0ur ride has arrived. with the chopper on the flight line, it's time for yves to become thejetman. no flight would be complete without an inspirational soundtrack. cheery music i notice that as well as lacking doors, this particular helicopter lacks seats in the back as well.

ok, 20 seconds until launch. that is without a doubt the most bonkers thing i have ever seen. so, we can just see yves in the distance. he is flying formation with the helicopter. there he is. he is going to fly parallel with the helicopter right now. oh, my word. you will believe a man can fly.

he has got about eight minutes‘ worth of fuel on board that. here he comes again. so, we arejust coming in to land now, but yves is going to land by a slightly different method. just in the distance out there, you can see him. his parachute is deployed, and he will land right back at his hangar. truly incredible stuff. as you can see, we have reached that part of the christmas dinner now. i will crack on though. my most memorable moment of the year was when i visited cern and the large hadron collider and had a jolly good cry. having a moment. we were really lucky to be able to see inside the collider and the cms experiment

because they they had opened it up for cleaning. even better, we filmed the whole thing in 360, so you can take a peek inside. welcome to the largest particle physics laboratory in the world. right now, you are standing inside cern, the european organisation for nuclear research. you have got a view that very few people will ever see. we are about 100 metres beneath the swiss—french border and above you is just one of the experiments at the large hadron collider. itself the largest machine in the world. in a few minutes we will head up there. on that cherry picker, to see what happens when you smash particles together at close to the speed of light. before we do, let me show you what kit you need to get things going that fast. so, here we are walking along part of the long circular tunnel that houses the lhc.

that is it next to you, that is the large hadron collider. that collection of magnets. it is a 27 kilometre long loop. there are four experiments on the lhc and ten accelerators in the complex which, together, accelerate bunches of particles to close to the speed of light. this cavern contains the cms experiment, the compact muon solenoid, although there is nothing compact about it, if you ask me. this is one of the places that helped to discover the higgs boson. so, that big shiny pipe above you is connected to the tunnels that we were just in. when the beams of particles are going fast enough, tiny adjustments are made to bring those two beams together until, right here, they collide. in an instant, the particles are smashed to pieces and it is these even smaller

particles that the cms can detect. it is an enormous sensor that looks for the fundamental building blocks of the universe. by using even higher energy collisions, the cern scientists hope to find other particles and explain mysteries like dark energy and dark matter which makes up 95% of the matter in our universe. this is big science performed on the tiniest of scales. that was cern in 360, and this is the clickmas table in 360. everybody wave at the 360 camera. the brilliant thing about filming in 360 is you can do really weird things with the picture on normal tv, like this. but you can also feel like you are genuinely sitting in the middle of our table on a candle. if you go to the link on the screen,

you can see us surrounding you, about to eat you. the man behind the 360 show is this man over here. steve beckett, who is wearing the beautiful augmented reality christmas jumper. why? what do you think of this? it is a little bit scary. terrifying. from one engineering marvel at cern and to another engineering marvel now that spans two mountains in china. dan simmons went to the oldest national park in china. tucked away on the edge of this world heritage site, someone has decided to build a bridge from the middle of nowhere to the middle of nowhere. unlike me, they hope, the thousands of visitors who will come here will not be too scared to look down. 300 metres through the highest glass walkway in the world. these are the final days of construction for this three—year

project, more than 300 engineers have worked through all weather conditions to build what is also the longest glass—bottomed bridge
