>>reporter: the western part of the capitol. as you can see behind me now security forces backed we the army and reinforcement by -- surrounding a house where they say five to six armed men are taking refuge. despite earlier today negotiating with the men to surrender. apparently it doesn't seem that these armed men are willing to surrender to security forces. there's been exchange of gun fire on and off. we do understand that one policeman was killed and one injured. . situation remains quite delicate. from time to time, the government opens fire and tries to storm the building. but the concern is that you have

civilians. ties with al quaeda could be behind the swings of attack that swept the political process, particularly because tunesia is going for landmark elections two days from now. well, as mentioned, tunesia is going to the polls on sunday. these polls considered crucial to the stability of this north african country. unemployment is a huge issue. we report live now from tunis. ♪ >>reporter: the music is about

poverty and unemployment. this group is recording lyrics in tunesian slang to dub over a well-known french cartoon. and the message is don't vote unless you know why you're taking part in the elections. >> when you watch television campaign ads, they don't reflect the streets. you only see the upper classes and people running for election driving porsches. >>reporter: that's why many young people are angry. he's one of many graduates who can't find work. she travels to this job centre every day. >> the education system has not changed for countless number of years. it's just becoming more and more mediocre. >>reporter: there's frustration that unemployment keeps rising.

when you speak to young people in cafes like this, many of them will tell you they don't know if they're voting on sunday. they feel like the parties aren't taking issue of unemployment seriously and they also don't trust many politicians. tunesia's government says it's trying to create job but the economic uncertainty has led to many young people illegally traveling to europe and may have contributed to the presence of more than 2,000 tunesian tunesian involved in the armed forces in syria and iraq. >> we are pushing our youth to be part of the elections.

♪ >>reporter: this is what the young are connecting with, this song talks about inequality and poor living standards. young people are were at the heart of tunesia's revolution. now many just feel let down by the process. the canadian prime minister is due to address parliament shortly and is being seen as a defiant move after wednesday's gun attack in the capitol. a gunman was shot and killed after being chased intoed the parliament building. he'd earlier killed a soldier nearby at the war memorial and another soldier died after being run over by a car on monday. both incidents were described as terror attacks by the prime

minister. meanwhile, a ceremony has been held in ottawa for the victim of wednesday's shooting. the prime minister laid a wreath at the national war memorial were the soldier was killed and witnesses say corporal nathan cirillo was gunned down by a man with a rifle dressed in black. we have been monitoring events in ottawa. it seems very much as though the canadians are determined to press on and try to show that they're open for business. it's business as usual with parliament sitting so soon after this event. >>reporter: that's right. nevertheless, canadians woke up to something of a shock. these are the headlines in the local papers. this is really changed the way canadians have looked at their security. this has not been a threat that they have felt has been something here in the homeland, something that canadians have

been involved with abroad having sent half a dozen planes to the middle east just a few days ago. now the concern is that they need to do more to protect their buildings here. they're making a show of having business as usual. nevertheless, they're talking about giving more protection to military personnel and to the government buildings which have been only lightly guarded to date. >> and tell us about the mood if you like with which mps are meeting in the parliament building which is very close to you and indeed the mood with which canadians are receiving this. they must be watching this right now, everybody in the country. >>reporter: absolutely. there's a somberness about it but also a determination. the prime minister was saying that canadians will not be intimidated. he is due to speak soon, and will likely press on with that message. he said that canadians will be vigilant not just here in canada

but around the globe. nevertheless, it is here in canada where the new found risk, at least in terms of perception, exists. so there's going to be a lot of talk about improving security here but canadians say they will press on. they want to continue to do business as usual. but the security at places like parliament is likely to change. already at military bases they have been closed down. troops have been asked to put on civilian clothes when they leave. so things have changed here in canada and they are likely to change for a long time. >> and are canadians asking those difficult, those awkward questions yet about how prepared were the security forces for the possibility of an incident like this? >>reporter: absolutely. those questions are beginning to be asked. but one thing they know is that the no-fly list has been working. this is a man whose passport was revoked. the authorities were concerned that he was heading to the middle east.

that he had been radicalize and was possibly going to join isil, the islamic group fighting in iraq and syria. >> okay, john. >>reporter: and they stopped him from leaving here. >> for give me, john, i need to cut you off because we're going to go to stephen harper himself who is addressing parliament. [applause] >> we are never ? [applause]

. >> we may sit across the aisle from one another, but when faceded with attacks on the country we all love and the things we all stand for, i know we will always stand together. [applause] >> mr. speaker, today, more than ever before, i am very happy to see all of my colleagues from all parties in good health across the aisle. >> maybe use that, mr. speaker, through you to provide a little bit of advice to my colleagues, i think my position and growing number of gray hairs entitles me to do this once in a while [laughter]? >> and that is just to say we all here are engaged in extremely demanding and stressful jobs. but the stress that many of you

faced yesterday was really beyond and above anything that any of us are really expecting to face. i will just say while we resume our duties -- and i'll talk about that in just a moment -- i encourage everybody here to take care of their health. be sure that you find some time to relax in the next little while and also if any of you -- because we are not all in perfect health -- if any of you are experiencing any uncue due fizz critical stress as a result of yesterday, please take the time to see a physician and check that out. [applause] >> i also just want to say to canadians, we heard a lot of feedback from canadians yesterday. we are all used to the regular feedback we get from canadia canadians laugh .

some of it deserved. i think in this case mr. speaker we all experienced the tremendous outpouring of affection and good wishes from across the country and we thank them, all of us, for that. [applause] >> i just also want to convey all the good wishes that i heard personally, not just from canadians but from our friends outside the country. i heard from president obama from prime minister abbott, from prime minister netanyahu, a statement from prime minister cameron. we've heard these expresses across the world. i think we were all as canadians expressed by the gesture at the pittsburgh penguins game. so thank you to our friends in

the united states and around the world. [applause] >> of course, mr. speaker, we know all too well that this is not a happy day for everybody, in particular, terribly sad day for all of the family, loved ones, friends, colleagues of both nathan cirillo and patrice vincent. >> we have seen photos of those lovely men. >> pictures of those beautiful guys as don cherry would say. and our hearts really are with all of them. we are so fortunate to have people like this. the past couple of decades has, you know, we see across the world increasing places where the planet is descending into

savagery. and there are people who every day of their lives stand on guard for this country and for all of us and we obviously want to convey our gratitude to these two servicemen and their families but also to all the people who undertake this extremely dangerous work. [applause] >> mr. speaker, i spoke of the state of much of the world, and i think for all of us that are blessed to live in a country

like this, it is hard to appreciate, understand, fathom, how we can have people who so dispise, who so hate progress that they can desire to drive out medical workers from their community, harm them, how they can enslave women, torture children, how they can kill, want to kill anyone who looks or thinks different than them. it is in a sense, mr. speaker, beyond our xre comprehension, but it is real. and in this struggle in which we are engaged in which not only our finest values must be pushed to work, so must be and will be

the highest unity and resolve they are our ultimate and indispensable weapons and that's what these people will face. [applause] >> mr. speaker, as regards the events of yesterday -- >> so that's the prime minister of canada addressing his parliament and indeed the entire country who will be watching this live with us. from montreal is rex brian. thank you for talking to us. how seminal is this moment for canada? >>reporter: i actually don't think that it is seminal. certainly it is, you know, a great deal of shock over the events of this week. certainly there's going to be

increased attention to what kinds of measures can be taken from physical security measures to counterradicalization, but i don't think that canadians ever thought they were immune to terrorism. this is a country which has experienced terrorist attacks in the past. and i think six months from now, a year from now, in fact, it's not going to look all that different other than it will be harder to get into parliament and some public buildings may be secured. the budget for the rcmp and canadian security intelligence service may be larger than it was otherwise. >> so you wouldn't agree then with those who suggest that this is canada's 9/11. >> it's certainly not canada's 9/11 by any stretch of the imagination. this is not a mass casualty event. if hundreds had been killed, i think that it would have a fuller effect. i do not think it's canada's 9/11. and certainly i don't get that

impresentation talking to other -- impression talking to other canadians that they feel that either. neither was this unexpected. i mean, this particular event was -- >> i'm afraid we've lost rex brian. that's a shape. a very interesting conversation we just started with rex brian from montreal. but i think we can still see stephen harper. i think we can go back to stephen harper, the canadian prime minister who is addressing parliament in a kind of show of defiance really and to rally canadians behind him just a day after the dreadful attack in which one soldier was killed.

>> 600 kilometres to kobani, about eight hours. so why can't kurdish fighters cross straight into syria? well, the answer is isil controls large sways of territory stretching from the syrian city of aleppo and mosul in iraq. so that's why they have to go through turkey to reinforce the kurds as they try to defend kobani from isil. so why is iraq's kurdish

government sending its fighters to help out in syria while they're strained trying to fight their own fight in iraq. >>reporter: still no confirmation as to how many will make that journey across to kobani an still no confirmation as to when they will be leaving. as yet, the agreement, the vote has yet to be signed by the president so we're still waiting to hear confirmation on a number of different levels here. one thing for sure though is there's a lot of fear whether they can be spared when there is such a long front line here that needs to be defended. can those forces be freed up to

defend and fight isil in kobani without jeopardizing their defence here. it's a front line that changes every day. it was fighting last night in mosul dam. we hear sources here that there were a number of isil fighters killed including an isil commander, but that was with backup from coalition air strikes, u.s. air strikes over here. there was also more fighting in and around the sinjar mountains backed up by yazidimilitia. the u.s. says it's hit isil with 15 air strikes over the past 24 hours. four were in the syrian town of kobani and u.s. planes also hit oil facilities held by isil east

of syria. russian news agencies are reporting that pro moscow forces in eastern ukraine are planning to retake three cities. the leader of the people's republic is quoted as saying they will attack ukraine's east. he accused ukraine's government of failing to observe a cease fire that was declared last month. the prime minister of ukraine has warned that possible attempts by russia -- our correspondent in the ukranian capitol, kiev. >>reporter: leaders here say they intend to retake territory which they've lost to government forces, that they want to recaptur recapture three towns that have been taken. all of this of course in the

leadup to sunday's election in ukraine, an election in which the breakaway leaders in the east won't allow to take part in territory in which they control but which will roll ahead in the rest of the country. in a pretty fraught political atmosphere, many accusations against the president over his handling of the war in the east, a feeling that he has perhaps been too soft on the secessi secessionis secessionists. the leader of pakistan's political party has survived a suicide attempt. he had addre survived the attac

while traveling in an armoured vehicle. at least three people were killed in the attack. this is the third attack in quatar today. benjamin netanyahu has accused -- a resident rammed his car into a crowd killing the infant. he was shot dead by police as he ran from the scene on foot. now, the latest statistics from the world health organization show a jump in the number of new cases of ebola in liberia. 444 new cases to be precise. they were reported in the week before the 19th of october. now, this is the highest number in the past four weeks. more than 2,700 people have now

died since the outbreak in liberia began. there's been more than 1,500 cases in guinea and 904 deaths. of the three countries, more than 4,800 people are reported to have died. w.h.o. says the total number of cases is close to 10,000. but we've been speaking to shawn casey who is the emergency response team director for international medical call in liberia. he's just gone to london and told us about the response to the outbreak which has got better but still more needs to be done. >> i've been in liberia for the last two months and it's dramatically different now than it was when i arrived. the response is scaling up. more financial resources are coming in. more organizations are coming online but we're still not where we need to be and it's a complicated response because

many agencies have never done this before. this is a unique scale for ebola. there's never been an outbreak like this. so we're learning as we go and hopefully in the next few months we'll be able to catch up. but it is slow at this stage. >> the mexican government has ordered the arrest of the mayor of a southern city and his wife. they're being investigated over the disappearance of 43 young people and the deaths of six others. thousands of tome people have been marching in mexico city demanding the officials do more to find these missing students. they have been missing now for almost a month. it was one of the world's best known brands but now nokia cellphones are about to go the way of if dinosaurs.

but they lost their lead to smart phones like apple and samsung. now microsoft has announced it will the start replacing the nokia name with its own starting with the lumia range of smart phones. now, helen keegan is an independent technology expert and says it's still not clear how much microsoft stands to gain from this move. >> this has been a long time coming and when we knew that the nokia building had been sold to -- the lumia brand is strong and combining it may work but only time will tell. the windows phone environment that we've seen microsoft come up with is a nice way to use a phone and there is room for more operating systems in the market

and one size does not fit all so not everyone will ever have an iphone or an android phone or whatever it might be. but they're the third play and are very small in comparison to both android and iphone meaning they are going to struggle. fortunately they have deep pockets meaning they can get traction and pay for the marketing that's needed. but i'm in the sure that the microsoft name will work as part of a hand set story. the lumia brand is strong. an x-box is strong for microsoft in the gaming world, but it's the x-box name, not microsoft. let's go back to the canadian parliament in ottawa. of course, the scene of yesterday's dramatic shooting and lockdown. there you can see canadian mps have gone back to the floor. have repossessed their building. and we've heard earlier from the prime minister himself stephen harper who was rallying all canadians really. so we've been following that

>> none of my actual patrons seem to mind. at the end of the day, if you are walking around with your wi-fi enabled, there is alternates more that someone can potentially do to you than, you transmitter. >> on the one hand, it's a little bit creepy because it's watching. >> i guess you are giving away your privacy. >> every mobile phone has a unique 12-character media access control address or mac address. it's your phone's fingerprint. the sensor reads the address and as another four randomly assigned kaingz on either side. that's encrypted with the national security agency's sha-256 encryption algorithm. what you get is a completely original 64-character id. happy child's data analysis is collected by a toronto startup

so let's take a look. >> grilled, sautéed prosprocessed or packaged. america's obsession with meat is ferocious. we consume over 270 pounds per person per year. but now, the demand for meat is spreading to new global heights and experts predict we won't be able to sustain it. >> i would say we are already not doing it sustainability. we are crawing on the planet's resources more than we should be alone. >> the united nations estimates meat consumption will rise nearly 75% by 2050. the rising trend has triggered a new crop of meat alternatives helping to ease our reliance. >> here in california, we have a small town with the
