lowest level since 2011. china's central bank evaluated the currency yesterday. pat sob has more on why this happened and what it means. >> a currency devaluation is like a shot of adrenaline to a sluggish economy, because it makes the goods exported cheaper to buy overseas. while they say this was a one off, the u.s. has accused beijing of keeping its currency artificially weak. u.s. exports suffered this year as the dollar has strengthened against our currencies, making u.s. goods more expensive to buy overseas. now a weaker chinese currency

charges. his father had argued that he actually wasn't even armed that night. the protests here in ferguson last night, a fifth night of protest were calmer than nights before. a couple of dozen protestors marched past police but they held back for the most part and there were far fewer police officers on the scene last night and fewer protestors, as well. in the end, it all broke up fairly peacefully with no arrests. last night, there was another appearance of the oath keepers. this is a very anti-government militia type group, walking around with big military type assault weapons. they claim they are just there to keep the peace, but the police and protestors clearly did not want them there. we caught an exchange between one of the protestors and one of those oath keepers. >> i'm protecting these

gentlemen so they can document what's going on. >> you're protecting the press from the police? if the press has been attacked by the police, you tell me these officers come over here and russia, you would defend them? >> the good news is there were no confrontations last night. again, no arrests here in ferguson, by there were two arrests in chicago at a michael brown sympathy ally there. >> a white police officer who shot and unarmed black teenager irtexas has been fired. the 19-year-old was killed during a burglary investigation. the 911 tapes were released tuesday and appear to contradict earlier reports that taylor was killed within one second after officers arrived on the scene. >> we got shots fired.

>> the recordings show nearly two minutes elapsed between police arriving and shots fired. officer brad miller shot taylor four times. the arlington police chief calls that initial chase questionable. taylor's family said it wants answers. >> this kid made a mistake and it cost him dearly, so nobody should have to go out like that. >> a criminal investigation is underway and arlington police officers advocacy group is appealing for fairness for the officer, stating that the investigation is incompletely. >> a federal judge denied bail for a young couple that tried to join isil. they were arrested at a regional airport in mississippi before taking off for syria. >> another case possibly connected to isil, a florida man

pleaded not guilty in a plat to bomb a public beach. the man allegedly told undercover f.b.i. agents he wanted to detonate a backpack null of nails in miami. >> the second charge is attempt to provide material support to a terrorist organization. it relates in my estimation to the allegation of a recruitment video. he is doing margin ally better. he has a chance to correspond with his family through letters. >> he was arrested in july after allegedly taking an explosive device from an undercover f.b.i. agent posing as an isil member. president obama's promise to close guantanamo bay before he leaves office has run into another road block. >> it was one of the first promises the president made. he campaigned on it and has

repeated it many times over the past seven years. in 2009, he signed an executive order to close the guantanamo detention center as soon as practicable. the pentagon failed to come up with a plan to make it happen. >> the one idea was to send several dozen of the most allegedly dangerous detainees who the pentagon says cannot be released or sent to other countries to the thompson correctional center, a federal prison in illinois that has 1500 empty cells. >> as reported by the washington post, the obama adding forget that former attorney general eric holder promised the senate judiciary committee we will not move people from guantanamo to

thompson, so it's back to the drawing board. >> we strongly support the secretary, standingly supports president obama's determination made from his very first day of his administration to close guantanamo. it's obviously a top priority. >> officials say it will be next month at the earliest before a proposal goes to the hill. mccain promised to work with president obama to close guantanamo, but only if the administration can provide an alternative that addresses congressional concerns. it's not just the current ban on moving prisoners to u.s. soil that has to be addressed, it's also the congressional requirement that the defense secretary tear sign off on any transfers to other countries, essentially certifying that the

reasked detainees no longer pose a risk to the u.s. that was a source of tension between former secretary hagel and the white house. hagel was often reluctant to give his personal assurance of something that was unknowable. current defense secretary tear ash carter is taking a conservative approach. six years after president obama signed and executive order to close guantanamo within a year, the number of detainees has been cut from 240 to 116, and nearly half had been cleared for release, with most not facing any charges. >> the state department says it is working full time to find countries who will take guantanamo prisoners cleared for release with nowhere to go. the white house is still searching for a prison in the u.n. willing to accept what it calls the irreducible minimum, the several dozen detainees judged too dangerous to ever be released.

>> that was jami mcen fire reporting. among those cleared years ago was the yemeni native in guantanamo for 14 years and on a hunger strike since 2007, force-fed through a tube, he only weighs 75 pounds. obama administration officials are divided over what to do with his case. his lawyer spoke to us about his client's grave condition. >> by the unanimous determination of six national security agencies, i'm talking the office of the joint chiefs of staff, director of national intelligence, department of defense, justice, home land security, all the agencies that u.s. citizens rely on have said he can leave guantanamo. >> why has he not been allowed to leave? >> what's remarkable is that that question is playing out right now in realtime in washington, d.c. i filed a motion for his release because he's so gravely ill, and asked the government not to oppose it, to speed his release so he can get to medical clear.

it appears that the department of defense dug in its heels and is defiantly blocking a common sense solution. it's shocking. >> the justice department has until august 15 to respond to the prisoner's petition and on the other side of the i'll, stay tuned for special custom out of a cuba as the u.s. flag begins to fly over the embassy in havana. we have a special hour of coverage at 9:00 eastern. >> coming up, painting the blueles away. we will take you to a town in mexico trying to revamp its gritty image one brush stroke at a time.

properly, then it's common to find legionalla in the water. >> health officials believe the outbreak came from one of the first towers tested. >> the source is never pinpointed to just one cooling tower or one source. >> one company says disinfecting a single tower can take six hours and cost up to $5,000. al jazeera. >> the deflate gate showdown is actually happening in new york federal court right now. tom brady and nfl commissioner roger goodell first met privately with the judge in the case to try to settle the matter. the nfl players union wants the suspension overturned the league imposed on brady. investigators say brady knew about the plan to deflate balls before the playoff. >> we always set the bar high and when we don't hit it, we

admit it and we do better. i think what we have focused on is how do we continue to do better. we've made changes to the way we operate. we've made changes to our personal conduct policy. we brought in expertise that helped us make better decisions. people expect an awful lot from us and we want to deliver that. fans want to see football. that's the best news about the time period we're in right now. it's all in front of us. >> his suspension does not include the preseason. he will be on the field thursday against the packers. >> the remains of an ancient egyptian queen may have been found, buried near the resting place of king tut who some believe was her son. much more testing is neat to confirm the claim. >> thanks for being with us. the news continues next, live from london.
