>> good evening i'm terrell brown with a western edecision of the broadcast. this is an anxious weekend for many american diplomats and travelers overseas. the state department has ordered 22 embassies and consulates across the muslim world closed today, a business day in those countries. cbs news has learned u.s. intelligence believes a major plot is under way and far enough long that a terrorist team has been selected and is in place. the u.s. has also issued a global travel warning for americans for the first time since the tenth anniversary of the 9/11 attacks. jeff pegues in washington begins hir coverage. >> reporter: white house officials say the president was briefed this morning on the potential terrorist threat idfore departing for camp david. worldwide, nearly two dozen u.s. embassies are preparing to close their doors in the next 24 hours. the state department says there is a potential for a terrorist intack, particularly in the addle east and north africa, hd officials have specifically mentioned yemen as a potential earget, the country's home base for al qaeda of the arabian peninsula also known as a.q.a.p., a terrorist group that

tny now consider the most dangerous in the world. while u.s. officials won't offer more specifics, a travel alert has been issued for american citizen worldwide, a warning that both rail and airports could be targeted. but at dulles airport near the nation's capital, the warning is not discouraging passenger nathan brandeburg. >> i'm not too afraid to be traveling, especially with security the way it is. i mean, we're traveling with a wt of gear as well and we have to go through a lot of security g i know what it's like. it doesn't really bother me too much. >> reporter: historically, the acnth of august has been an active one for terrorist yganizations. w years ago this week, twin u.s. embassy bombings in kenya and tanzania claimed over 200 lives and injured more than 4,000. next month also marks the first anniversary of the september 11 attack on the u.s. consulate in whicazhi, which killed four americans, including the u.s. ambassador.

here in washington, there bpears to be rare bipartisan oreement on this potential alreat. white house concerns have been echoed by republicans. the universal message: u.s. personnel connected to embassies and consulates should be sigilant. terell? >> brown: jeff pegues in washington thank you. joining us from washington is our senior national security analyst juan zarate. juan, what do we been this intelligence? >> terrell, this intelligence anpears to be serious and credible coming from coming from the upper echelons of al qaeda, and in particular the al qaeda l qaliate in yemen. i authorities are taking it sery seriously. ehe problem, terrell, is they lln't have specific enough hformation about the plot or the target, so authorities are looking for that information now to try to disrupt the plot. >> brown: juan, is there something about this time of year that the intelligence community is particularly worried about? >> well, the end of ramadan, the holy month for muslims, is often a period of increased violence. the eid holiday is a period of edolence.

but i would say, when al qaeda is ready to attack, it tries to attack. the challenge for authorities will be understanding what this plot is and if they're not able to divine or ferret out what's happening at what point they lift the alert and open up the diplomatic doors again. >> brown: juan zarate in on forgton for us tonight, thank you. >> thank you, terrell. ib brown: egypt's military leader and the man responsible tr the ouster of president morsi has rebuked the white house for its response. in an interview with the "washington post," major general abdul fattah al sisi said: for more on that we turn to urnrissa ward in cairo. clarissa, what's the latest? >> reporter: that's right, terrell, in a two-hour interview, sisi accused the u.s. of ignoring the will of the egyptian people by refusing to endorse the military takeover, a measure he said he took to prevent this country from descending into civil war. sisi said he speaks to secretary of defense chuck hagel every day but president obama has not called him once since morsi's

ouster. >> brown: we know that secretary of state bill burns is work with both sides. how are those negotiations oting? >> reporter: burns has been meeting with all the top players, including general sisi, and working closely with a top european union diplomat trying to get both sides to agree to a n.litical settlement to prevent further bloodshed. but we do not know how successful those talks have been. >> brown: clarissa ward in cairo for us tonight. narissa, thank you. the obama administration has amaoed a ban on importing certain older models of apple delsnes and ipads. the u.s. international trade commission imposed the ban in june on the grounds that the chinese made items violated a patent owned by samsung. today's ruling is the latest chapter in a more than two year long battle between the two companies. rex rodriguez takes the field again tonight for the a.a. trenton thunder.

ranishment, said to range from a lengthy suspension stretched through next season to a lifetime ban. >> alex, do you think you're eding singled out? >> what do you think? oy job is to do everything i can physically and mentally to get back on the field to help my ielm win. as far as all the legal stuff, to me, it's been confusing. g.e one thing i've gotten from so many people, so many fans, some teammates, they're like, "what is going on?" >> reporter: what's going on is major league baseball is accusing rodriguez of more than cest using performance-enhancing drugs from a florida clinic. sources close to the investigation say there's evidence he recruited other players to use the drugs and tried to obstruct the investigation. last night, rodriguez intimated the deck is stacked against him. >> i will say this-- there's atre than one party that-- that enefits from me not ever stepping back on the field, and that's not my teammates and it's not the yankee fans. >> reporter: he likely was nkferring to the yankees tganization which stands to

recoup anywhere from $34 million to the full $100 million left on his contract, depending on the severity of the league's punishment. e are are reports today, major league baseball and the yankees are so angry about his comments that they are no longer negotiating with him for a shorter penalty. an official announcement on all the player suspensions is expected on monday. terrell. >> brown: don dahler, thank you so much. health officials have confirmed more cases of cyclospora. the stomach bugged sickened more than 400 people in 16 states. investigators are struggling to find the source of the outbreak. some of the cases were traced to a salad mix from a mexican farm. it was served at olive gardens and red lobsters in nebraska and iowa. the other illnesses are still a mystery tonight. carter evans has the latest. >> reporter: the f.d.a. says a talad mix that came from the taylor farm processing plant in mexico contained a parasite called cyclospora. that is what authorities say siused an outbreak of severe stomach illness. the salad mix was delivered to

the olive garden and red lobster in iowa and nebraska. r's still unknown why the contamination occurred. the f.d.a. says it's not yet fear whether the cases reported from other states are part of the same outbreak. how surprised were you to hear about this outbreak? >> very surprised. >> reporter: food safety consultant jeff nelken said cyclospora infections are rare, and symptoms take one week to appear. >> if you ask someone what they ate, you can do that, but can tou imagine going seven to 10 days out, and you're looking at ,verything you've eaten. people don't have a diary that they can refer to. >> reporter: in a statement, taylor farms admits it was the supplier of the salad mix that was the source of the outbreak but the product is no longer in the supply chain and bagged salad is safe to eat. according to the u.s.d.a., mexico is by far the largest

exporter of fresh vegetables to the u.s., accounting for $4 rllion last year. it's been one month since the last reported case of cyclospora, and there's little concern about a wider outbreak. but what remains unclear is just why and how so many have gotten so sick. carter evans, cbs news, los angeles. >> brown: the standoff between cbs and time warner cable continues this evening, one day after the cable company dropped cbs in eight cities, including new york, los angeles, chicago, and dallas. some three million customers in all are affected. at issue is the fee time warner cable pays cbs to carry its programming. there's no indication a ittlement is imminent. an increasing number of dolphins are washing up dead on east onst shores this summer. it's an upsetting trend and the cause is still a mystery. here's vinita nair. >> reporter: more than 120 dead eolphins have washed ashore between virginia and new jersey

in the past two months. they're mainly bottlenosed dolphins and they are different ages and sizes. > there's a number of things that cause animals to strand. it could be biotoxins. it could be disease. it could be human interactions with fishing gear. >> reporter: maggie mooney-seus of the national oceanic and atmospheric administration says the recent rash of dolphin deaths is very similar to an episode that happened in 1987 when more than 900 dolphins died. in that case, a bacterial infection was mostly to blame. virginia has seen the biggest spike this summer. 42 dolphins died in july, compared to 10 in july 2011 and 2012 combined. how concerned is noaa, that this is happening? the concern here is that it's an elevated number of one species, so we are watching this very closely and collecting much information as we can. >> reporter: sometimes the dolphins are found sick but alive. this one was found trapped on a

sandbar in long island but a rescue worker nursed it back to health. >> we still try to collect as much data information as we can from them. so we're hoping that there's still going to be a positive from those deaths. >> reporter: experts say the carcasses pose no potential health risk, and the affected beaches are safe. one of the biggest issues has been cleanup. each dolphin can weigh up to 500 pounds. vinita nair, cbs news, new york. >> brown: in bakersfield, , aifornia, a scheduled building implosion wound up injuring five people when it sent shrapnel flying. more than 1,000 spectators came out to watch and thought they were safe 1,000 feet away. one man's leg was severed. later, an alternative to styrofoam made out of fungus. another strange twist in the "whitey" bulger story as his trial comes to a close. dnd prince william leaves the wlace for the first time since forseen birth. those stories when the cbs evening news continues.
