round—up of the day's news. first, it's time for our world: iraq's war on meth, with yalda hakim. a hunt is under way. basra police, on the back of a tipoff, think they've found their target. a suspect they believe has been dealing in the highly addictive and illegal

drug, crystal meth. kidnapping, extortion, organised crime are already part of daily life here in basra, iraq's second city. now there's a new threat, crystal meth. i've been invited tojoin the police frontline. this is the elite force that goes out every night on raids to try and crack down on organised crime in this city. they think the suspect is inside. major mithak is leading the raid.

with him, officers from the counter—narcotics unit and swat team. in just two years, police have made more than 4,000 drug—related arrests. at police headquarters, they're keen to show off the results of their efforts. today, hundreds of suspects are being paraded in

front of the cameras. the police want to show the local media, and i suppose the community, the arrests they've made and the progress they're making to crackdown on crime in basra. general abdul karim is leading that effort. a war veteran, he recently returned to basra from the fight against isis in the north of iraq. 0k, we're going to go and meet some people who've been arrested. wow, 0k. when did you arrest these guys? where were these guys arrested? police say consumption of meth has been doubling year—on—year. so you found all these weapons?

that's crystal meth. how many grams? 0ne. ig. so why has crystal meth taken hold in this city? weak border security has meant drugs have flooded into the country, and economic collapse with youth unemployment at almost 50% means there's a ready market for the drug. after years of war, occupation and insurgency, the locals here had hoped their city would become the next dubai. but there are no skyscrapers here, just high unemployment, crime and corruption. at basra general hospital, psychiatrist dr al sabbagh has been seeing more patients come forward with meth addiction. what is the scale of the problem?

in 2015, the iraqi government, together with the us department of health, ran a study looking at addiction in basra. there werenncehigi'rhtfpgs oil production in basra province generates 95% of the country's oil wealth. but most residents don't see any of that. this is jumhuriyah, one

of the poorest most densely populated parts of town. most of the young people here haven't finished school, they're out of work. jumhuriyah is notorious for gangs and drug dealing. shallal rady, who is 21, has never worked. so do you feel safe here? what about drug users? hello, how are you?

nice to see you. i went to see shallal‘s family. they're struggling to get by without electricity or any clean water. his father has serious health issues. what do you think about iraq now in comparison to what it was like when saddam was in power? the swat team are on the move again. this city is awash with weapons left over from the war and the fight against isis. the team are looking

for their second target. young men of the house are hauled out of their rooms. but the man they are after is missing. what has happened? it is hard to ignore basra's

crippled infrastructure. addicts live in these impoverished districts where crystal meth addiction flourishes. many addicts and dealers end up here at this prison. this man is the deputy governor. what are the issues you face here? prison authorities have had to expand detention centres

to cope with the numbers of addicts and dealers. major, this is one of the rooms? how many people in this room? and this is a combination of drug dealers and drug users? yeah. you just keep them all here together in one room? yeah. i am taken deep into the prison to see what the conditions are like for those who have been convicted. quite overwhelming. i mean, i've been to many prisons in many parts of the world

but to see these people just crammed into here, they take shifts sleeping so one person will sleep and one person will stay up all night and then they swap. it is incredible. i mean, the conditions are really bad. do they go out at all? what kind of drugs did you have? crystal. how did you start using crystal meth? what about your family?

what were they seeing? your wife didn't know? ali hammoud has already served ten months of a five—year sentence for dealing. how did you become a dealer? and did your family

know you were dealing? sobs the drugs trade has been driven partly by the security vacuum left when forces were sent to fight isis in the north of the country. general abdul karim wants to show me the smuggling route. general, where are we going? but with so much security here, general, how were they able

to get across the border? the porous border here between iraq and iran means the southern province has become a prime smuggling route. back injumhouria, i've come to the shisha bar to catch up with 21—year—old shallal who i met earlier. i am meeting up with his friends who are all angry with the government in baghdad. what about drug abuse? that is a big problem here in basra as well. it is 3:00 in the morning

and the swat team are honing in on their final target in jumhouria. meth addiction is fuelling crime in the city. and it is young men mostly who are the perpetrators. 15 years after the fall of saddam hussein, iraq is in a fragile and perilous state. with all the attention on the fight against isis in the north, basra and the predominantly shia south feels forgotten. and it is the young

who are paying the price. another iraqi generation at risk of being lost. hello. it was a weekend with more sunshine around on saturday, cloudy conditions on sunday with some outbreaks of rain, too. this was a picture taken off the coast of norfolk. fairly typical across many parts of the country, grey cloud, and that cloud did bring

with it some showers. through this week, that unsettled theme continues, so often pretty breezy and showery, particularly in the north—west, with the driest weather often to be found in the south—east. but, first thing monday, we've got low pressure to the east, and that will bring some sharp showers to eastern parts of england and up across parts of scotland, some rain lingering here to, where it's going to be fairly cloudy. it will be an improved day for parts of northern ireland, wales and south—west england, with a ridge of higher pressure developing here, and some of these showers through central and eastern parts of england could be heavy and thundery, bringing a mix of hail and heavy rain in quite a short space of time. so the chance of some localised flooding here. temperatures around 17 to 20 in the north—west. we could see up to around 23 celsius in the south—east. through monday night and into tuesday, this area of high pressure from the azores tries to push into southern and south—western parts of the country, but it's also met with low pressure moving in from the north—west, so that's going to bring weather

fronts, outbreaks of rain to parts of northern ireland and the west of scotland through the day on tuesday. eastern scotland and down across england and wales, likely to stay dry for a good part of the day, if not all day in the south. temperatures a little bit warmer by the time we get to tuesday. we could see 26 celsius down towards the london region. just a bit fresher for scotland and northern ireland. into the middle of the week, and wednesday sees heavy rain pushing in across parts of northern ireland, scotland, north—west england as well. further south and east across england and wales, you've still got the warm and dry weather, but quite a brisk south—westerly wind. temperatures up to 25 or 26. to the north—west of that front, just 16 degrees there in stornoway. a bit of a change through wednesday night and into thursday, as this cold front gets driven further south and east across the uk. it's driven on by this kink in the jet stream. so that will bring a spell of heavy rain and then it will open the door for that cooler and fresher weather moving in from the north—west, so thursday initially some outbreaks of rain across the south—east of england and east anglia, and then fresher conditions moving from the atlantic,

with a mix of sunshine and some heavy and possibly thundery showers for scotland and northern ireland. a bit fresher by thursday, so 17 to 21 degrees as we look towards the end of the week. during friday, low pressure still to the north—west, so more of that rain and breezy conditions for parts of scotland and northern ireland. much of england and wales, particularly down towards the south—east, you're more likely to stay dry. temperatures perhaps up to around 23 in the warmer spots, but the high teens across scotland and northern ireland. looking into next weekend, the jet stream moves a bit further north across the uk. that will allow higher pressure to start to moving across more of the country for a time, but then another kink in the jet stream developing in the north atlantic, which could well bring more low pressure to the north—west as we head into next week. this is monday and tuesday of the following week. still rather cool and breezy across scotland and northern ireland. warmer and drier with a bit of sunshine across parts of england and wales.

the outlook generally a bit of a mixed one. it's often looking quite breezy, frequent showers in the north and north—west and the driest and warmest weather to be found towards the south—east. you can find a full 14—day forecast on our website. bye—bye for now. this is bbc news, i'm chris rogers. the headlines at ten: police in manchester say a shotgun was probably used in a shooting in the city's moss side area last night, 12 people, including two childern, sustained pellet—type injuries. two, one, zero — lift—off! nasa's space probe begins its ambitious seven yearjourney to the sun after it finally takes off from cape canaveral. dina asher—smith wins her third gold of the european athletics championships in the four by 100 metre relay. and at 10:30 and again at 11:30 we ll be taking a look at the papers
