captioning sponsored by cbs this is the "cbs evening news." >> axelrod: good evening. i'm jim axelrod. we begin tonight in colorado, with some promising news in the fight against the most destructive wildfire in the history of the state. four days after the fire started burning, firefighters now say they are getting the upper hand on the flames. at last count, 473 homes have been destroyed in a roughly 24-square-mile area near colorado springs. and two people have been killed. tonight, the fire is said to be 45% contained. manuel bojorquez begins our coverage. >> reporter: more than 300 firefighters were added to the front lines this weekend for the first time this week, the fire did not assume more land or homes, but it has changed the landscape. el paso county sheriff terry maketa: >> it look like a nuclear bomb went off in some of those areas and you can't even recognize whether it was a house or some

other kind of structure. >> and i am pleading for some accuracy. >> reporter: at a packed town hall meeting today, frustrated residents wondered whether their homes were destroyed or among 3,000 still standing in the black forest community. >> once they tell me the area is safe, then we're going to open it up for residents to go in. >> reporter: emergency management officials say that process won't begin until early next week. they warned residents against entering the evacuated zone because the fire is still a threat. that has left homeowners uncertain. >> i, for one, don't know whether i have a standing home. >> reporter: ted robertson already knows. he saw his house go up in flames as he fled. >> we saw several of those black plumes, and you-- your stomach just tells you. that's your house. that's your neighborhood. and, you know, it's gone. >> reporter: what is that like to watch? >> um, we're still numb. it was nopght but ash, and i was able to get a couple of photographs of that, and make

the toughest call i've ever had to make to my wife to tell her we didn't have a house anymore. >> reporter: what was her reaction? >> it was extremely strong, very intense. and for her her, it's an irrevocable change. it's a loss we will never see reversed in our lifetime, and it's so permanent. it was like the same thing she experienced when she lost her mom. >> reporter: ted robertson told me he's not sure whether his family will want to rebuild in black forest. but knowing their house is gone is a first step in the process of moving forward. jim, tonight officials are asking for information from the public which could help determine the fire's cause. >> axelrod: just brutal. manuel, thank you. the colorado fire is just the latest in a series of wildfires across the west that have put an enormous strain on resources. as carter evans reports, the reach of the sequester extends all the way from washington, d.c. torkts flaming front lines. >> reporter: fire season has

exploded across the country. so far this year, more than 19,000 wildfires have scorched the equivalent of 700 square miles, forcing thousands out of their homes. five firefighters have already died, including 28-year-old luke sheehy in northern california. he was killed when a tree fell on him. sheehy was part of a small, elite team of smoke jumpers who parachute into remote fires. >> we've had numerous fires already. i foresee a very busy season for us. >> reporter: miguel martinez is a firefighter in california where the number of wildfires is up 45% this year. the reason-- unusually dry weather. nearly half the country is already experiencing moderate to exceptional drought conditions. tom harsher is fire chief for the u.s. forest service. >> we've seen a significant change for the worse in terms of how hot fires burn, how quickly they explode. >> reporter: but federal firefighters are facing another challenge, a lot of $50 million

mandated by the budget sequester. that forced the forest service to cut 500 firefighters and 50 engines, just when they're needed most. >> we're going to have to work harder. we're going to face more fire with fewer firefighters. >> reporter: adding financial pressure to an unusually dangerous fire season that won't peak until september. carter evans, cbs news, los angeles. >> axelrod: egypt is cutting off diplomatic relations with syria. the latest bit of line drawing in the arab world over syria's civil war. the maneuverings of egypt's president, mohammed mursi, carry implications for u.s. policy in syria and beyond. major garrett joins us now from the white house to explain. major. >> reporter: jim, president obama is tbrawlly increasing u.s. military involvement in the syrian civil war. but egypt's moves today, and the white house silence in reaction to them highlight the risks

involved. egyptian president mohammed mursi called for a no-fly zone over syria and broke diplomatic ties with dictator bashar al-assad's government. the u.s. will now send military equipment to syrian rebels and it contemplating a no-fly zone to nullify superior syrian air power, this after the white house said assad's regime used chemical weapons against the rebels. egypt's aggressive moves against assad might look helpful but egyptian sunni muslims are likely to back al qaeda-linked rebels fighting in syria. these are precisely the jihadist opposition cells the suz trying to isolate. the syrian conflict has also deepened a long-standing rift between the united states and russia. the pentagon announced f-16 and patriot missile systems sent to neighboring jordan for military exercises will stay behind. russia fears the fighter jets could be used to impose a no-fly zone, and in a speech today, the foreign minister preemptively

declared such a move illegal. russia backs assad's regime, which has increasingly relied on iranian-backed hezbollah fighters to retake rebel-held terrain. for the first time, secretary of state john kerry said both syrian developments reveal, "the regime's lack of commitment to negotiations and threatens to put a political settlement out of reach." the white house has long wanted to contain the syrian civil war and to diplomatically coax assad from power, but that strategy is losing steam, and president obama hopes next week's g-8 summit with russia will be an opportunity to regain lost momentum. >> axelrod: an egyptian airline or a flight from cairo to new york was diverted to glasgow, scotland, today after a passenger discovered a threatening note in the bathroom that said, "this flight will be on fire." more than 300 passengers and crew were on board. now to iran, where they've

elected a successor to hard-line president mahmoud ahmadinejad. after eight years in office, ahmadinejad was prohibited by law from running again. eight men ran to succeed him. elizabeth palmer joins us now from london. liz, a man named hossan rohani will be the next president of iran. is he in the mold of ahmadinejad? >> reporter: well, he was seen as the most reform-minded of all the candidates who ran this time. that being said, they were all very conservative. in u.s. terms, it was as if all the candidates for the presidency came from the tea party. nevertheless, young people, especially, see mr. rohani as presenting a little bit of a hope for liberal reforms. he is a cleric. he is 64 years old. he's a very experienced diplomat. , quite cariz mat and i can also extremely close to the centers of power in iran. >> axelrod: so what will this mean for iran's relations with the west going forward? >> reporter: well, mr. rohani has been in powerful positions before.

back in 2003-2005, he was actually the head of the iran's nuclear program. and back then, under his leadership, iran agreed to suspend uranium enrichment in order to try to allow productive talks to go ahead with the west. so people who watched the nuclear standoff now think maybe mr. rohani can do it again and turn out to be a pragmatist and compromiser who can find a solution to the nuclear stalemate. >> axelrod: elizabeth palmer reporting for us tonight from london, thank you. nelson mandela's grandson said today the former south african president is recovering well from a lung infection. mandela, who is 94, has been in the hospital for eight days. but a former body guard who was put on leave for leaking information to the media is highly critical of mandela's doctors. he spoke on our debora patta. >> shaun van heerden has been nelson mandela's constant

companion for the last 12 years. are his wishes being respected? >> no, he's not being respected. >> reporter: over the past few months, van heerden says as mandela's health has deteriorated, access to him by visitors has been restrict by his medical team. >> it got to the point where the medical staff was like they own nelson mandela. they call the shots when it comes to who sees him, who don't see him. >> the africans require. >> reporter: he says the anti-apartheid campaigner, once jailed for 27 years is very lonely. >> it's actually sad because it felt for me-- and i still do-- that they've put him right back in prison again at his old age. >> reporter: do you think he is going to make it through this? >> personally, i hope so, but i don't think so. >> he believes mandela would not want to spend his last days in a hospital. >> take him home.

and then if we've to close his eyes, so be it. set him free. as tough as it is, let us set him free. >> reporter: we attempted to speak to nelson mandela's medical team to hear their side of the story but our calls have gone unanswered. and as for mandela's health tonight, the south african government's description remains the same-- it is still serious. jim. >> reporter: thank you. several hundred demonstrators in hong kong marched today in the u.s. consulate in support of edward snowden. he is the former national security agency contractor who leaked top-secret information about u.s. surveillance programs. some held signs reading, "betray snowden, betray freedom." in london today the duchess of cambridge made what's expected to be the last public appearance before giving birth to her first child and the next heir to the british throne. kate, who is eight months pregnant, was among the royals

scare me as a kid, but the word "chemo" did. they were going to give me ceem oh, which means they were going to stick a need nel my veins and put chemicals in my body and make my hair fall out. but it also killed the cancer cells. >> reporter: after chemotherapy, radiation, and a bone marrow transplant, her cancer was eradicated. but golden, now 31 and an aspiring opera singer, has multiple health issues attributed to her treatment. then you find out you have very high cholesterol. you have thinning of the bones. and your thyroid's enlarged with nodules, probably from the radiation. what are you thinking? >> you know going into the treatment that there's going to be side effects, and every cancer patient is going to have different side effects, and i guess these are the side effects i got. >> reporter: but these side effects can develop years later. and a new study shows that for golden and many others, the effects often go undetected.

more than 1700 adults, formerly patients at st. jude children's research hospital, were monitored for complications of their therapy. two-third of patients had developed a chronic or life-threatening condition. until the study, patients were unaware of almost all of the heart problems and more than half of the lung problems. >> i do want the pediatrician to follow up. >> reporter: dr. melissa hudson is the study's coauthor. >> childhood chaernses after they graduate from pediatric programs they're going into a community where medical providers are not going to be aware of their unique health risks. >> you don't think about taking care of yourself when you feel fine. >> reporter: and is there part of you that just wants to say that was me as a girl who had cancer. that's gone. i don't even want to think about it again? >> sometimes. >> reporter: how do you fight that? >> i guess the thought for me is just knowing that if i don't take care of myself i will never be able to reach miep dream.

>> axelrod: dr. jon lapook joins us now. so how does a study of treatment 25 years ago affect how cancer is treated now? >> reporter: we've learned so much about how to be more targeted. back then, we gave chemotherapy and radiation and steroids, and, yes, we cured the cancer in a lot of cases but we really harmed the patient. and now with these more targeted therapies, the trick is to leave the normal tissue perfectly fine and to just target the cancer cells, try to hit it with a sniper rather than a howitzer where you end up blowing up the whole person. >> axelrod: the quest for precision. jon, thank you. up next, one man's mission to wheel himself across the country. nc research suggests ch designed for women's health concerns as we age. it has 7 antioxidants to support cell health. one a day 50+. it has 7 antioxidants to support cell health. help the gulf recover, andnt to learn from what happenedg goals:
