>> glor: the hunt is on for a notorious drug lord. a year after he was re-captured, the mexican drug cartel leader known as "el chapo" breaks out of prison again, this time through a tunnel. a day of high-stakes diplomacy and drama. in vienna, negotiators from the u.s. and iran close in on a nuclear deal. in brussels, last-minute meetings on whether greece stays in the eurozone. severe thunderstorms and flash floods forecast from the upper midwest to the ohio valley. >> it's like a river back there! >> glor: and after a spacecraft's 9 1/2-year million- mile-a-day journey, pluto is finally ready for its close-up. >> we're not going to see anything like this again, i don't think, in our lives. captioning sponsored by cbs this is the "cbs evening news."

>> glor: hi, everyone. i'll jeff glor with the western edition. his cartel is believed to be the number one supplier of heroin, cocaine, and marijuana into the u.s. his arrest last year was heralded worldwide. he has now escape from prison for a second time. late last night, joaquin "el chapo" guzman broke out of a maximum security prison about 60 miles from mexico city. here's carter evans. >> reporter: mexican authorities were confident no one could possibly escape the country's only supermax prison. it had never happened before. until last night, when joaquino" "el chapo" guzman, head of the multi-billion-dollar sinaloa cartel, disappeared, despite prison walls that are three feet thick. alejandro rubido is mexico's national safety commisioner. "the escape alert was activated" he said and the prison staff proceeded to check the cell. inside, they found a tunnel."

a very elaborate tunnel with ventilation and lighting, even a rail system to transport tools and dirt. the tunnel began inside a house under construction a mile away from the prison. it ran 30 feet underground and emerged just below a shower area inside el chapo's prison cell. the drug kingpin had been there for more than 16 months. guzman's cartel is believed to be responsible for more than 30,000 deaths. his arrest last year at a hotel in mazatlan was hailed by both u.s. and mexican authorities. he was paraded before cameras. and former mexican ambassador to the u.s., eduardo medina mora, was confident. >> he's locked up in the most reliable prison we have in mexico. and suddenly, once bitten, twice shy. we'll take our precautions in this case. >> reporter: now, authorities are scrambling to find out what went wrong and who was involved. more than 30 prison guards have been interrogated, and late today, mexican president enrique peña nieto vowed to track guzman down.

"i am deeply dismayed," he said. "this is certainly an affront to the mexican state." el chapo had escaped prison once before. in 2001, he bribed his way out of a mexican jail leaving in a laundry cart. that manhunt lasted 13 years. in that time, his cartel grew and is believed to be responsible for 70% of the illegal drugs that enter the u.s. through mexico. that's why u.s. authorities were elated to see him behind bars, as d.e.a. agent derek maltz told "60 minutes" correspondent bill whitaker. >> so getting him was a big deal for you. >> absolutely. in my world, it was like winning the super bowl, winning the world series. this was the actual trophy. >> he was number one? >> absolutely. >> glor: u.s. authorites wanted to extradite guzman when he was arrested so he could face charges in this country, but mexico wanted to put him on trial there first. today, u.s. attorney general loretta lynch said the united states will provide any support mexico needs to assist in

guzman's swift recapture. >> glor: carter evans, thank you very much. new optimism today about a possible nuclear deal with iran. margaret brennan is in vienna. >> reporter: on the 16th straight day of talks, secretary kerry struck a positive tone. perhaps seeking divine intervention, kerry went to pray at st. stephen's cathedral, a historic 12th century church in vienna, and iran's top diplomat appeared relaxed sifting through the 100-page draft agreement. but there are still a handful of tough issues holding up a deal. one of the most contentious is iran's demand to phase out an arms embargo that blocks it from buying missiles and conventional weapons. earlier this week, general martin dempsey warned against that. >> under no circumstances should we relieve pressure on iran relative to ballistic missile capabilities and arms trafficking. >> reporter: diplomats are trying to find a compromise, but the speaker of the house republican john boehner, told "face the nation" that the u.s.

has already given away too much. >> no deal is better than a bad deal. and from everything that's leaked from these negotiations the administration backed away from almost all of the guidelines that they set for themselves. >> reporter: u.s. congress will get 60 days to review any potential deal reached here in vienna, and diplomats hope to know by tonight whether any final agreement with iran will even be possible, or if that country's leaders will ultimately reject a decade-long freeze on its nuclear program. jeff? >> glor: european leaders are debating whether to extend a financial lifeline to greece. holly williams is in athens. >> reporter: greece's economy has been brought to its knees and its people are suffering. like everyone else here, for two weeks now, christina vasilopoulou has only been able to withdraw around $60 a day from cash machines.

how are you going to survive without money? >> reporter: greece's creditors -- chiefly germany and france -- have already bailed it out twice in the last five years with loans of over $250 billion. but greece has never recovered from the financial crisis of 2008. a quarter of the workforce is unemployed. in return for an extended bailout, greece's creditors demanded tax hikes and cuts to pensions and public spending. greek officials walked out of negotiations last month. and greece's radical left-wing prime minister, alexis tsipras accused international creditors of blackmailing his country. but facing financial collapse, this week he was forced into a humiliating backdown, agreeing

to nearly all of the creditors' demands in return for a new bailout of $60 billion. greece's economy minister, george stathatkis, told us this week he was confident the country's creditors wouldn't let it go bankrupt because that would trigger financial losses around the world. what are the chances that greece will be able to strike a deal with its creditors? reporter: how high? >> well, i'm not a gambler, but i think well above 80%. >> reporter: but the danger for greece is that its creditors could decide they no longer trust the greek government and refuse to bail the country out for a third time. many greeks are angry with their foreign creditors but also frustrated with their own government. because, jeff, even after capitulating to its creditors demands, greece still doesn't have a deal to avert bankruptcy.

>> glor: holly williams. thank you. severe thunderstorms and flash floods are in the forecast from the upper midwest through the ohio valley today. parts of kentucky are already under water. we're joined now by morgan lentis of our cbs louisville affiliate, wlky. morgan? >> reporter: jeff, the water is already receding around the city. and as you can see behind me some creeks are already still staying out of their banks following this morning's severe rainfall. we're hearing that some areas received three to four inches of rain between about 4:00 and 9:00 a.m., causing substantial damage to some homes and buildings. flooding has been an issue this year in louisville so it's not unfamiliar, but many residents that we spoke with today tell us this is some of the worst flooding they've seen in years. and, unfortunately, there's no relief in sight just yet. forecasters calling for more severe storms over the next 24 hours, possibly even damaging winds. >> glor: morgan, thank you very much. julie martin of the weather channel is tracking the storms. what's the latest, julie? >> reporter: a couple of dangerous days ahead.da

we'll see these storms push through minnesota. but by tomorrow we're looking at as many as 50 million people under the gun for hail attaching winds and tornadoes. looking at fargo, arriving in the minneapolis area 10:00 or 10:30, pushing into the chicago metro likely by morning and then continuing to push off to the south-southeast with as many as two to three rounds of storms expected. in fact, if you look at the future models, we do see them starting to get better organized as they do get into southern indiana and kentucky, possibly even forming what we call a derecho. that's a strong line of storms that can produce winds, even exceeding hurricane force. and they mean business-- back in 2012, one in the mid-atlantic killed 28 people and caused close to $3 billion in damage. we want everyone to be aware on monday, the threat is certainly there from chicago to cincinnati. louisville, all the way down into nashville. now's the time to prepare. we want everyone to take this seriously and stay safe. jeff?

>> glor: julie, thanks very much. baseball's all-star game is tuesday night in cincinnati. before the game, pete rose will take the field for a ceremony, a rare moment in the spotlight for a man banished from baseball more than 25 years ago. here's contessa brewer. >> reporter: in his heyday, pete rose was the subject of little boys' hero worship and old ladies' adoration, a charismatic off-field personality and the all-time hits leader with 4,256. jared max is a sports journalist for cbs radio. >> pete rose is charlie hustle because he played the game like every game was game seven. >> reporter: in 1989 he was banished from baseball for betting on the sport as a manager. 13 years later, then commissioner bud selig met with rose to talk about reinstatement. in january, selig talked to charlie rose about his decision. >> i just felt, obviously, by not doing anything, that it was

in baseball's best interest and everyone's best interest to leave the suspension as it was. >> reporter: current commissioner rob manfred has agreed to discuss letting rose back into baseball, which would make the 74-year-old eligible for the hall of fame. but now, new revelations. espn has recently revealed in its investigation that pete rose gambled not only as a manager, but as a player and gambled on his own team. will that influence commissioner manfred's decision? >> should it influence? no. may it? yes. we have people in the hall of fame who are drunks and druggies and wife beaters and worse. why discriminate against somebody who suffers from gambling disorder? >> reporter: this year, for the first time since his banishment from baseball, the all-star game is in pete rose's hometown cincinnati. he'll join other reds legends on the field for the kind of

official recognition that's been rare over the last 26 years. but in a city, where the street outside the stadium is named pete rose way, fans still call him "charlie hustle." when commissioner bart giamatti originally banned pete rose, he said rose stained the game and had to live with the consequences. today, the question is, for how long? jeff? >> glor: contessa brewer. thanks very. >> glor: there was a dramatic rescue operation off the massachusetts coast. marine experts fought off a hungry shark to free a humpback whale that was tangled helplessly in a rope. julianna goldman reports. >> reporter: the teenage whale was essentially hog tied and probably had been for a couple - - making it unable to defend itself against predators like this great white shark. that had already attacked it. >> we've been disentangling whales since 1984 and never seen -- never had a shark around us. >> reporter: the 15-foot shark was still circling when scott landry and a group of marine biologists discovered the whale just floating a few miles off the northern coast of cape cod. >> we made a simple cut that

allowed the whale to resume its normal posture. >> reporter: by the time they were finished, the shark had retreated, and the whale swam away. there are usually between 20 to 30 cases of entangled whales per year in these waters, often caused by fishing rope, a particularly enticing toy for the younger mammals. >> teenagers being what they are often do get into trouble. >> reporter: and landry says this was one lucky teen. julianna goldman, cbs news washington. >> glor: it's a fly-by nearly a decade in the making and show time for pluto. and the weightlifter known as "the beast" sets a new world record. when the "cbs evening news" continues. r poligrip seals out more food particles. so your food won't get stuck and you can enjoy every single bite. eat loud, live loud, super poligrip. super poligrip holds your dentures

needle, what is? >> reporter: it's hard to grasp traveling 3 billion miles. to put it in perspective imagine the sun the size of a quarter. placed on the goal line of a football field, earth would be three yards away. pluto would stretch 18 yards beyond the far goal line. tom krimigis has been on the front lines for nasa since 1965. reaching the solar system's coldest destination will be an historic feat. >> and the adrenaline is really running high. and as soon as they see a new set of data and it goes up on the screen, you know they burst into applause and high fives and everything else. >> reporter: the journey is remarkable for another reason. there's an astronaut on board, the ashes of the late clyde tombaugh, who wanted this mission more than anyone. he discovered pluto in 1930. his ashes are on board this mission. how special is that? >> he's going to be the first human being to ever leave the solar system. what a fitting tribute for the man whose hard work and diligence paid off in the discovery of pluto.
