it is about 3:30am. now on bbc news: our world. hadicha is fighting forjustice. her husband, azimjan, has been in prison for ten years for crime he says he didn't commit. now he has one last chance of freedom. but as the court case approaches, coronavirus is spreading.

this is the story of hadicha and azimjan and their fight forjustice. kyrgyzstan, a central asian country which borders china. most of the 6 million population are kyrgyz. but there arejust under1 million uzbeks. one of them is hadicha. for ten years she has campaigned for her husband, azimjan askarov, a human rights activist who is in prison.

hadicha and azimjan have been married for over a0 years, but in 2010 he became caught up in violent clashes between kyrgyz and uzbeks. azimjan set out to find out.

while azimjan was documenting the violence, police visited hadicha.

now azimjan found himself being interrogated by the same local police he had been investigating. he says he was mistreated. shortly after his arrest, he told a localjournalist what happened.

azimjan was sentenced to life imprisonment for murdering a policeman and inciting ethnic hatred. he has always strongly denied the charges and says he was not given a fair trial. hadicha has spent the last ten years campaigning for azimjan�*s release. but despite international pressure and a un human rights committee calling for him to be freed, he remains in prison. hadicha and azimjan are both artists.

hadicha and azimjan have four

children and ten grandchildren.

but right from the start, they find justice is hard to come by.

the court postpones the verdict and rules that hadicha has to pay $1,600 to the family of the policeman who was killed. if she doesn't, half of her house will be confiscated. hadicha's monthly pension is $60.

every few weeks, hadicha makes the long journey to prison 19, where azimjan is being held.

but this time, they hit a problem. the coronavirus is now spreading across kyrgyzstan, which puts an end to prison visits. once a month, hadicha and azimjan talk on the phone.

despite the pandemic, the court pushes ahead with the final hearing in may. the court upholds azimjan�*s life sentence. it's the end of hadicha's hopes for justice. hadicha continues to wait and work on new parcels for azimjan.

today she's baking traditional uzbek food for azimjan. with coronavirus spreading rapidly through kyrgyzstan, amnesty international and human rights watch step up their calls for azimjan to be released on health grounds. he is 69 and considered to be at risk.

the kyrgyz government told the bbc:

azimjan was buried in uzbekistan on the muslim festival of eid al—fitr. his family believed holding the ceremony on a holy day was a good sign for his spirit.

well, it's certainly been cold in the last couple of days. we've snow, particularly across northern parts of the uk. but here's the good news if you don't like the cold. it is going to feel a lot better on wednesday. we won't have that cold northerly wind. we won't have that windchill, which we've been experiencing for a couple of days now. but the arctic air has spread right across the continent into northern parts of the mediterranean as well, so it's quite a widespread outbreak of cold arctic air. now, through the early hours you can see clear skies across much of the country. still a few wintry showers there across parts of scotland. but lighter winds, clear skies, a frost as well. temperatures in some cities down to around —2 or —3 celsius early on wednesday morning. so wednesday's looking something like this, lots of bright, sparkling sunshine first thing in the morning. but the clouds will build

through the morning and into the afternoon. so actually the second half of the day is looking a little overcast for some of us. and in the north—west of the country, later on in the afternoon, and towards the evening, the clouds will thicken further and we are expecting some outbreaks of rain in places like belfast, glasgow, much of the western isles. and that's because a weather front is approaching, the winds turning direction, actually milder air is reaching us. and by very early on thursday morning you can see that generally across the country it is frost free — almost. now, that change is brought by area of low pressure which will be tracking into the north of the uk. you can see that slightly milder air brought in by these south—westerly winds. so i think on thursday temperatures, at least for a while, will recover to double figures, onlyjust. perhaps 11 or 12 across parts of england and wales. but with that also comes a weather front and outbreaks of rain parts of the north—west of the uk. i think the best of the weather will be further south and also south—east. now, as we head into thursday night and friday, that weather front will move across, in fact, it's a cold front and behind it we once again open up the gates to a cold air

stream from the arctic, which could bring wintry showers to northern areas of the uk. so, yes, temporarily it is going to turn just a little bit milder through thursday, friday, maybe saturday, but the second half of the weekend it is turning colder again.
