Barcelona who were making bombs to go into vehicles and the fact that explosives are becoming part of this aim of committing terrorist acts, thatis aim of committing terrorist acts, that is a real concern, because a big bomb causes huge loss of life. People are expecting and possibly vigilant for suitcases, backpacks, and this looked like something belonging to a builder. What worries me, actually, is that we always look at the last attack and concentrate on that. Terrorist can use different methods, it is up to them. It is really important that everyone understands that vigilance is important, wherever you are, trains, most people would not even look down ona train, most people would not even look down on a train, but if everyone is vigilant and does their way to report someone who is acting suspiciously, then we have got a chance of saving lives and protecting people. And that was Chris Phillips talking to our reporter. Youre watching bbc news with julian worricker. Well have much more from Parsons Green but now lets cross to the bbc sport centre and the very latest. Former england manager roy hodgson says he fully believes he can keep Crystal Palace in the premier league. He takes charge of his first match tomorrow, having replaced frank de boer, who was sacked earlier this week after opening the season with four Straight League defeats. I have said to the players already, i have not given many team talks as such, but the one point i did make to them, was our focus is on may, not at the end of september, because leagues are not won at the end of september and teams are not relegated at the end of september. The weekends premier League Football begins with a friday night match on the south coast as bournemouth host newly promoted brighton. It will mean a lot to the fans of both clubs. Bournemouth are without a point yet this season but brighton come off the back of their first top flight win, so are bournemouth feeling the pressure already . There are several ways that you can look at things. The best way to put it, if you go game for game, last year, we were one point down. As much as we do not want to panic and i think that is key, we have to be very controlled and measured in our approach, we recognise that we need to win soon. Commentary for that is on radio five live at eight oclock. Just a warning of some flashing images coming up now.

Theres one for the purists in las vegas this weekend, thats being dubbed as the real deal with the winner of the middleweight title clash between Gennady Golovkin and Canelo Alvarez likely to be seen as the best pound for pound boxer in the world. Ade adedoyin is in las vegas for us. Excitement is now well and truly building. Yes, welcome to las vegas. You join me at the mgm grand arena where it will take place later.

This is the mexican Independence Day weekend celebration, thousands of people have come to las vegas for the festivities. There will be a concert later, people have turned up to support Canelo Alvarez, there they are the supporters who outnumber the others. Lots of people with banners. They outnumber at their Gennady Golovkin supporters and behind me, there is a mariachi band who have been playing here and it has all created this great atmosphere. This is not only a great fight between two of the best pound for pound fighters in the world at the moment but a great occasion on account of it being the mexican Independence Day weekend. The mexicans need for Canelo Alvarez to deliver the performance they won. He isa deliver the performance they won. He is a mexican idol who appeals to all demographics, i spoke to a lady who said she was and i asked her she was a boxy banerjee said no, ijust like Canelo Alvarez.
