difficult, if not impossible, in the worst—affected areas. our correspondent judith moritz reports. grounded at glasgow — flights at the city's airport were suspended after snow settled quickly overnight. the airport reopened by mid—morning, but managers have apologised for the knock—on disruption which was caused. temperatures plummeted to as low as minus 12 celsius in scotland. the ploughs were out, shovelling industrial quantities of snow on the m90 motorway near dunfermline, though it wasn't enough to keep all drivers on the road. in towns and villages nearby, the spades were out to clear the way. she's just come in for a packet of cigarettes, and she's decided to clear my front path away, and that's community spirit for you. heavy snow also fell in the north of england, where a hundred gritters were sent out onto the road network to keep traffic moving.

the snow has been falling steadily all morning across swathes of northern england. as predicted, it's been settling most in areas like this, just outside huddersfield, up here on the higher ground. in cumbria, hazardous conditions left some vehicles stranded on the a590, and there were also delays on other main roads. staff at the highways england control room in wakefield have been monitoring the motorways and a—roads. the next thing we're looking towards is the threat of ice for this evening and overnight, we've got teams of gritters working 21w, traffic officers patrolling the network as well, and obviously a team here in yorkshire and the north east working from the control room to make sure that that impact‘s not too severe. drivers are advised only to travel if necessary. judith moritz, bbc news, wakefield. anti—government protests have spread to more cities in iran, despite a crackdown by the authorities.

thousands of people have taken to the streets to protest over rising prices, corruption, and the cost of iran's military involvement in regional conflicts. wyre davies reports. these are extremely rare sights. iranian cities hit by large anti—government protests. this is the western city of kermanshah. despite the repressive action of the police, the protests have quickly grown and spread. iranians have suffered tremendous economic hardship in the last decade with a huge fall in living standards. but what started as a protest against rising prices has grown into wide anger against strict clerical rule and iran's supreme leader, ayatollah ali khamenei. there is seething discontent, with iranians spending money on wars abroad, on spreading shiaism broad, supporting hezbollah abroad.

and that has changed the character of the demonstration into a political one, undermining the whole clerical regime now. iran's relatively moderate president, hassan rouhani, has promised the benefits of economic growth after an international deal to limit its nuclear activities. but those promises have failed to materialise. britain will be watching developments closely. on a recent visit, the foreign secretary borisjohnson raised the detention of the british woman nazanin zaghari—ratcliffe, held in an iranianjail for more than 600 days. it's become a serious issue between london and tehran. it's too early to say if the regime is under serious threat. these are the biggest protests in iran for almost a decade and the government will greater force if it feels it is losing control. wyre davies, bbc news. a huge fire at an office and restaurant complex in the indian

city of mumbai has killed at least 14 people including young women attending a birthday party. the blaze erupted after midnight in the popular kamala mills compound, and engulfed the building injust half an hour. the new york fire department says the blaze that killed 12 people, including four children, in the bronx area of the city appears to have been caused by a child playing with a stove. investigators believe an unattended 3 —year—old boy accidentally started the blaze — described as the deadliest in the city for at least 25 years. the labour peer, lord adonis, is stepping down from his role advising the government on major infrastructure projects. in a draft resignation letter, the former transport secretary criticised theresa may's approach to brexit, and claimed that she has become the "voice of ukip" within the conservative party. two men have been charged with

preparing an act of terrorism. they appeared by video link before westminster magistrates‘ court and we re westminster magistrates‘ court and were remanded in custody. researchers in scotland, who saved the leg of a dog using a new technique to grow bones in a laboratory, say they now hope to try it on human beings. the dog, eva, would have had her leg amputated had it not been for this pioneering treatment. the team at glasgow university say the first human trials are due to take place in three years‘ time. 0ur science correspondent pallab ghosh has this exclusive report. eva! there‘s no holding her back, but last year eva‘s front right leg was broken in a road accident. her vet tried everything, but nothing worked. her entire leg was going to be amputated. well, nine, ten months, she‘d been unable to get out and have walks, anything other than go out to the toilet. but to fiona kirkland‘s delight, her dog was saved by an experimental

bone—growing technique. it‘s absolutely fantastic. we‘re just so pleased to have our dog back, fit, active, healthy. eva‘s vet showed me the problem. the blood supply to the edges of the bones has failed, so it wasn‘t able to heal the break. the scientists coated the dead areas with their artificial bone, and afterjust six weeks, it was completely mended. the artificial bone mix was made at glasgow university. it consists of sterilised chips that are coated with bone cells and a chemical that make them grow, rather like a fertiliser. well, clearly, we want to look at treating more dogs and possibly even cats who have had broken bones, but also other areas we can help these veterinary patients, so things like joint fusion, where they‘ve had a tendon injury and they need theirjoint held together so they can walk properly. the researchers are so amazed

at the success they‘ve had in treating eva they want to try out the technique on people. they plan to be the first researchers in the world to grow bone in their lab and put it into a patient in three years‘ time. and these are the people that could be most helped. it‘s 20 years since princess diana brought the issue of landmine victims to the world‘s attention. their limbs usually have to be amputated. landmine campaigners are funding the new research so it can be used to grow some of their bone back and attach an artificial leg. well, if they are able to have a prosthetic limb, it would make all the difference to their life, being able to provide for their family, instead of having to be a burden on their family. it‘s been a happy outcome for eva and her owners. thousands of people could soon benefit from a technology that has

put a spring back in her step. pallab ghosh, bbc news, glasgow. you can see more on all of today‘s stories on the bbc news channel. now on bbc one it‘s time for the news where you are. this is bbc news. more now on the heavy snow that has fallen today across parts of the country, delaying flights and causing problems for some drivers. with children off school, and many of their parents away from work, lots of people have been making the most of the snowy conditions. from west yorkshire, 0livia richwald reports. four days too late for
