welcome to bbc news. police in australia say they've foiled an islamist—inspired plot to bring down an aircraft with an improvised device. the prime minister, malcolm turnbull, said the plot appeared to be "elaborate", rather than planned by a lone wolf. phil mercer reports. investigators in australia say they had information about a plot to blow up an aircraft involving the use of an improvised device. four men have been detained following raids across sydney by heavily—armed police and members of australia's domestic spy agency. it is reported the operation was not planned, but a rapid response to a tip—off. the prime minister, malcolm turnbull, said the authorities have foiled what appears to be an elaborate conspiracy.

i can report last night that there has been a majorjoint counterterrorism operation to disrupt a terrorist plot to bring down an aeroplane. the operation is continuing. four people have been arrested and a considerable amount of material seized by police. upon advice we have received from intelligence and countering terrorism agencies the government move swiftly to protect the public while operations are underway. additional security measures were put in place at sydney airport on thursday. a woman who said her son and husband were among those arrested in sydney has denied they had any links to extremism. but senior police commanders say the raids were part of an alleged islamic—inspired plot.

additional security measures have been put in place at domestic and international airports around the country. people can expect an increased police and security presence. longer delays to make sure more screening is being done on hold luggage and hand luggage. be aware, go to the airport as normal, but give yourself more time. the advice is urging travellers to remain calm and go about business as normal. australia's national terror threat level remains at probable, which means the intelligence agencies believe that groups or individuals have the intent and capability to carry out an attack. since 2014, 70 people have been charged as a result of over 30 counterterrorism raids across the country. joining me form canberra now is jacinta carroll who is the head

of the counter terrorism policy centre at the australian strategic policy institute. can you explain what is the terror threat overall in australia? it is one that you do not hear about as much in the international environment because, of course, we have not had a major successful terrorist attack to date u nfortu nately terrorist attack to date unfortunately like the uk and europe. but the threat is possible, equivalent to the uk level, and has been that for just under three yea rs. we have been that for just under three years. we have seen in that time 12 previous mache casualty plot —— mass

casualty plots foiled. we have foiled successful terror attacks. these have been single acting low—level terror attacks, including weapons such as knives of firearms. the most well—known of those was 2.5 yea rs the most well—known of those was 2.5 years ago at the cafe. it is co nsta nt, years ago at the cafe. it is constant, the threat, and it will be maintained at the probable level, we have heard today. the type of attack thatis have heard today. the type of attack that is being planned is more sophisticated and complex, involving something like explosive devices, which we have not seen in the current threat period. other than last christmas we have a similar plot disrupted in melbourne. we have seen the so—called islamic state terrorist groups and others specifically name airports,

melbourne and sydney as targets. it appears there are groups here seeking to take up that call. how would you characterise the authorities' efforts to contain the threat? the disruption and are reasonably —— disruption efforts had been incredibly successful. the new south wales police... 0ver been incredibly successful. the new south wales police... over the last decade and a half, a joint approach so decade and a half, a joint approach so that the domestic temperatures equivalent of mi5, in relation to counterterrorism, it is working. and the federal police runjoint counterterrorism units with the state and territory police. a joint,

integrated unit undertaking the disruptions. they work together well. again, as has been your experience, they have been incredibly busy, running around 400 investigations, almost double of what it was a couple of years ago. the threat is very high. the work tempo is high. the useful thing, as we heard from the federal police commissioner today, the more complex attacks such as this one with a number of people trying to get into a secure facility such as an airport and using difficult to obtain goods such as explosives, and requiring the technology to undertake this attack, means there should be more indicators for investigators to be alert to it. concerning me with this one, we hearfrom the alert to it. concerning me with this one, we hear from the authorities that they found out about this just last wednesday. within three days,

they decided they really needed to move in order to be able to prevent a successful attack. thank you very much. two person has been killed and several injured in a shooting at a nightclub in germany — the attack happened in konstanz, in southern germany near the border with switzerland. the attacker is said to be an iraqi national living in the country for some time. the motive for the shooting is still unclear. the international trade secretary liam fox has said unregulated free movement of people between the uk and the eu after brexit would "not keep faith" with last yea r‘s referendum result. mr fox told a sunday newspaper he'd not been party to any cabinet discussions about a transitional arrangement in which immigration rules remain similar to what they are now. with me is our political correspondent emma va rdy. liam fox seems to be striking a

different tone to previous ministers in this last week? that is fair to say. the idea of freedom of movement was a hot topic during the brexit referendum campaign. we were bombarded with arguments about getting back control of the borders. the government has says freedom of movement rules will still apply, not apply any further after 2019. in practice, that does not mean eu citizens will be prevented overnight from living here. it means a gradual phasing to prevent a cliff edge for business. philip hammond that the chancellor says it will be sometime before we are able to introduce full migration can trust between the uk and eu, a period of up to three yea rs and eu, a period of up to three years where things are phased in gradually. in an interview with the sunday times, the international trade secretary liam fox appears to be at odds with this. he said, if

freedom of movement rules appear not to change much at the brexit, that would not keep the faith with the result of the eu referendum. he said he has not been party to cabinet discussions about an arrangement which keep rose the same similar to 110w. which keep rose the same similar to now. seems to be an agreement that there is a need for this transitional period after brexit. we are seeing divisions on how this might work and, crucially, on the issue of immigration how it might look to voters. do we have any idea of how it might look? amber rudd has said eu citizens will move to britain post—brexit, a registration and document process. the government says it will set up a bill, white paper setting out its approach. but the uk has not begun negotiations with the eu over what the transitional deal will look like, or

at what pace. new immigration rules we re at what pace. new immigration rules were coming in due course. that will not be the morning after brexit, there will be a gap and something will need to fill that. we don't know what that will look like at the moment. that is where the divisions are emerging. later today the belgian city of ypres will pause to remember one of the most costly battles of the first world war. by the end of the three month campaign — half a million men were dead, injured, or missing, in the mud of no mans land. now — a century later, the land is still yielding deadly reminders of the fighting. our special correspondent robert hall reports. 0ne one of the things that affection most is the number of missing. thousands upon thousands of men whose bodies were not recovered or never identified. 0ver whose bodies were not recovered or never identified. over the next couple of days, under the menin gate where the names of more than 54,000 of the missing are inscribed, and

around the city of ypres, commemorations to remember all of those who fell during the campaign to capture the high ground and the village of poelkapelle. —— passchendaele. they call it the zonnebeke. debbie constantly appearing on the service from under the flanders clay. i went to visit those still clearing up 100 years after the battles. drie, twee, een. this is a corner of europe where first world war shells explode every working day. the belgian bomb disposal team is based in poelkapelle

deal with at least 200 tonnes of unexploded munitions each year. you may think that after 100 years this iron harvest would be reducing. it's simply not true. during the first world war, along the western front, 1.5 billion shells were fired and of those, one in three failed to explode. that left 500 million still in the ground. a few miles from poelkapelle, another call. a farmer has left several unidentified shells for the squad to collect. this is a 4.5 inch british.

if we look at the length and the fuse, this is high explosive. this as well. we have no chemical shells here. one third of the munitions that the team recover contain chemicals such as mustard gas. the firstjob is to clean them up, and not always that gently, for a rough idea of how dangerous they might be. here we look for characteristics and then for an exterior marking. they do that with a hammer or a copper brush and, it sounds old —fashioned, but it is still much safer than using a sandblaster or high—pressure water. the next step is an x—ray. you can see now the bottom. this is chloride and cyanide or arsenic. around is explosive. even after 100 years, lives are at risk here. the chemical shells are eventually destroyed in a sealed chamber. conventional explosives

follow a separate path. shells, bombs, grenades and bullets forced to the surface of local farmland by frost action and ploughing. how much explosive is in one crate, do you think? always around 50 kilos of explosives. more than 50 kilos, even deeply buried, would risk damage to buildings. and still this meticulous operation rolls on. the legacy of a distant war that will provide these lethal reminders well into another century. this weekend about commemoration but also about trying to bring home what

happened to the visitors who will attend. zonnebeke, there is a memorial museum and gardens there, one of the focuses of attention tomorrow. they have told us about the war under the ground. you had to the war under the ground. you had to the indication of the fighting under the indication of the fighting under the surface being so fierce that men had to borrow under the ground to stay alive. there is a dugout that has been sealed since the war apart from a little archaeology. it has been unsealed forjust100 days. the director of the museum invited me to ta ke director of the museum invited me to take a look. here we are at the original entrance of the church. these steps where used by the troops 100 years ago? yes. this is all original. actually, they are in good condition. during the battle of ypres, passchendaele, everything

in the region was destroyed. we are six metres underground. this was used as a shelter. the small rooms off the passage, these were where men could have these were where men could sleep? beds or storage rooms. they had some shelter and resting places. a massive job to open this to the public because it has never been added to the public before? no. the dugout was discovered in 1989. the archaeologists were trying to do some research to the medieval... they found the original entrance of the dugout. when you opened this up, what did you think? extraordinary state to be preserved in, isn't it? because of the water? this is the main reason. the dugout is usually completely

underwater because the level of the ground water is high. because the wood is underwater from more than 100 years, that is the reason it is so well preserved. a lot of work for people here. why did you feel it was so important that today's generation saw this, just for the 100 days, just briefly? so important for us as a museum. we want to connect with the heritage and the landscape as well. a unique example of such a heritage point in the landscape. a unique opportunity to set it open to the public so they can see and feel how it must have failed to live under the ground, six metres under the ground. you could hear the water rushing, the palms running continually to keep the dugout try. that is what it was like 100 years ago. safer under

the ground, but not pleasant. rats, flooding, collapses. buta the ground, but not pleasant. rats, flooding, collapses. but a good indication of what those men had to put up with during their time up at the and in the trenches. 0ver put up with during their time up at the and in the trenches. over the next couple of days, this evening, the duke and duchess of image and queen of belgium here under the menin gate. we are under the road to the soldiers would have marched up on their way to the changes. the audience of the agyeis —— vips, families, we'll watch the ceremony which has been going on uninterrupted for a long time. and then towards the market square in zonnebeke. it was rebuilt after the war. with the church wanted it left in ruins after the war. the belgians wa nted in ruins after the war. the belgians wanted to come back and rebuild the

city and move back in. it looks much as it did before the war. a ceremony there, a mixed media ceremony with music, poetry and the words of those who fought in the battles raging over the town. you can watch that on bbc two, but ben brown will keep you up—to—date throughout the day on other events happening in zonnebeke and around the city. —— ypres. an independent review into greater manchester's response to the manchester arena attack will be chaired by lord kerslake — the former head of the civil service. the mayor says they will try to learn lessons from the attack. he's currently the chair of king's college hospital nhs foundation trust and hejoins me now from south west london.

what is the scope of the review? what is the scope of the review? what will you look at? it will look at what happened as a response to the attack. it was a terrible event in which 22 people lost their lives. provo ked in which 22 people lost their lives. provoked a massive response from the police and other emergency services. we wa nt police and other emergency services. we want to look at how did those services respond, and in particular how well aware they prepared —— how well aware they prepared for these type of events? there are things we can learn and things we can see susan see how things will be dealt with. it will look thoroughly and fairly at the issues. who will you hearfrom? from fairly at the issues. who will you hear from ? from the fairly at the issues. who will you hear from? from the emergency services, but importantly we want to

get the voice of the families, victims, those who have been injured andindeed victims, those who have been injured and indeed anyone caught up in the terrible events of that night. important to us that we conduct the review a nyway important to us that we conduct the review anyway we —— in a way that shows we have this and. —— shows we have listened. i want to consult with others about how best to get the views of those affected. as a panel, we will do that when we get to meet, to do it anyway they feel works for them. you spoke about examining the preparedness of the emergency services. will you be looking at whether this attack could have been prevented ?|j looking at whether this attack could have been prevented? i think that is a different kind of review. the factors that led up to the terrible

attack will be for a different kind of review. we are focused on the response to the review and how well prepared greater manchester was for such an event happening. finally, what will happen to the findings of the review? will they be binding? well, this is a report commissioned by the maher. andy burnham. —— the mayor. we will report back to him and the service is responsible for dealing with emergencies. i expect they will take those recommendations very seriously because it will be evidence —based, the review. it is about having to do with things in the future. it will bring forward lessons relevant is notjust a greater manchester but to the country as a whole. 0ur greater manchester but to the country as a whole. our aim is to do

an interim report around christmas time and then a final report fairly soon after that. it is quite important that we move quickly to catch people's experiences while they are fresh. we will start in september and then to do it relatively quickly. thank you very much. sport now, and for a full round up, from the bbc sport centre. england's cricketers will start day four of the third test against south africa in a strong position, despite rain wiping out most of the afternoon's play at the 0val yesterday. starting in 30 minutes. they have a lead of 252 runs. if we can get up towards the 400, in reasonable time, then we will probably be happy with that. i would hope we could bowl them out in the session, in a day — we have some big hitters to come in towards the back end that can

speed up the run rate. that would be the way we would be looking to go about it, i would imagine. play starts at 11. a big day ahead for england at the women's european championships. they're in quarter final action later today against france england haven't won against them since mark sampson took over in 2013, and have been beaten by them in their last three major tournaments, but that's a record they're confident they can change. what the england team are really building, they beat germany two years ago for the first time ever, in friendlies, in major tournaments regardless. it is just another, they will go in with the same mindset. it's not anything different for this one game, it's just part of that momentum and that building process that he and the team have been a part of for the last, certainly this last six months, i have seen this mentality. that real internal drive, stepped up a gear. waiting for england should they beat france will be the hosts the netherlands.

they beat sweden 2—0 in front of a sell—out crowd. the dutch are now one match away from a first ever european final... they'll be one extra quarterfinal today after germany's clash with denmark was postponed after torrential rain in rotterdam. have a look at this. the dugouts were flooded. and the pitch, well that certainly wasn't in any condition to play on...as one of the ground staff found out! later this afternoon, great britain's adam peaty will bid to win his third gold medal in the 4x100 medley relay final at the world championship in budapest earlier this morning max litchfield qualified for the men's 400 metres individual medley final this afternoon. he finished second in his heat and was also second fastest overall. hannah miley just qualified for the women's 400 metres individual medley final. she was eighth quickest. the british women also

qualified for the 4x100 metres medley relay. jonny brownlee's hopes of becoming world triathlon champion look to be over after he finished fourth in edmonton, canada overnight the 2012 champion missed the last leg of the championship in hamburg through illness. he is well down the points list after only completing four races this year. spain's defending champion mario mola won the race and is on course to successfully defend the title once again. that's all sport for now. you can keep up to date with all those stories on the bbc sport website. including the build—up to the hun derian grand prix. lewis hamilton is in fourth, derian grand prix. lewis hamilton is infourth, and derian grand prix. lewis hamilton is in fourth, and i will be back in the next hour. donald trump has again criticised china over its relations with north korea.

on twitter he accused china of making hundreds of billions of dollars from trade but doing nothing to tackle north korea's nuclear threat. his comments come after north korea carried out its second major missile test in a month. the us air force says two of its bomber planes have flown over the korean peninsula in response. the people of venice —— then so that will vote today. more than 100 people have been killed in four months in anti—government protests in the country. a record number of criminals have had their sentences increased under a scheme which allows members of the public to ask for them to be reviewed. last year, 141 criminals in england and wales had their sentences increased. the government says it wants to extend the scheme to include a number of terror—related charges. aisling mcveigh reports. sarah sands stabbed a man to death in november 2014. she was convicted of manslaughter

and given a 3.5—yearjail sentence. her neighbour, michael, was a convicted paedophile and sarah, a mother of five, claims she lost control, stabbing him eight times. it was in january last year that the punishment was considered to be unduly lenient. judges at the court of appeal ruled that because she took a knife to his flat she must have intended to cause serious harm and her sentence was doubled to 7.5 years. 141 criminals have had their sentences increased in the last year, according to the attorney general‘s office. the unduly lenient scheme allows them to the public to query penalties for serious offences and more people are doing just that. requests are up 17% on the previous year. sex offences are the highest number of cases where sentences were increased and 14 sex offenders who had originally escaped prison are now serving time behind bars.

from next month, the scheme will be widened to include an extra 19 terror—related offences. the attorney general says in the vast majority of cases, the judges do get it right. the number of sentences that are increased represent a tiny proportion of the 80,000 cases heard every single year. the now, a look at the weather. it isa it is a case of deja vu with weather at the moment, sunshine and showers have been with us for several days and that is the story over the next few days as well. some heavy rain overnight has cleared towards the east, then there is a rush of showers in northern and western parts of the country that are making their way slowly eastwards through their way slowly eastwards through the day. some showers do parts of scotland, northern ireland and wales could be heavy and thundery. they will drift eastwards today.
