>> welcome to new al jazeera america. i'm dell walters. the fighting resumes in gaza with deadly results again. flying over war zones security concerns cause some airlines to reroute their flight bath path. and tracking down people who may have been exposed to the ebola virus.

food and medicine for gaza has closed and fighting has erupted all over again. the aftermath of a marketplace not long ago. 17 people were killed. 160 others were injured. there has been heavy fighting on the ground as well. three israeli soldiers were killed in that fighting. you're looking at a leaflet that the israeli army is dropping fulling gaza telling gazaens to get out. in the three weeks since the start of what israel calls protect edge 1318 palestinians have been killed, mostly civilians, and 7350 palestinians

injured. 53 israelis killed. >> reporter: one of the most largest group of victims that we've seen since the beginning of this conflict. you see horrific images of what happened. eyewitnesses telling us there was a single strike on this marketplace. people started running and there were more strikes into the crowd. this is the community that has been so heavily hit by israeli strikes, and as well palestinian fighters firing rockets and using tunnels into israel. this was supposed to be a cease-fire during this time. israel specifically said that the cease-fire did not apply. they issued other areas that they were operating in, but apparently these people did not get that message. they were out in hundreds of people were shopping for the first time in days trying to use

four-hour or five-hour cease-fire to get things you done before they hunker down in their homes. that's when the strikes happened. >> you were at the school that was attacked earlier, tell bus that. >> reporter: yes, this is a school just a couple miles behind me. the u.s. said israel struck the school with direct hit with no warning. the shell struck as the family inside this family slept. it was a classroom that became a shelter. it was supposed to be safe. the pad that this boy was sleeping on is now stained with blood. the shelling came in and exploded in the middle of the room. you can see the food they were eating, some of the clothes they were wearing. you have to remember that this

was a school. that had become a shelter. >> reporter: more than 3,000 people had been sleeping here. they fled to where they felt it would be secure. a woman and her family have been living here. >> do you feel safe here? where will you go now? >> in where--nowhere is safe. i have no home. where can i go? nowhere is safe. >> the youngest victims will not be comforted by their parents. the wounded wait for treatment by doctors who are overwhelm. >> they told us to attack shelter in the school but they attacked us. >> my husband and i are disabled. if we have the option to leave we will definitely will do so.

>> even the people who work here don't know what to say. >> when people today after this attack ask where should i go, what do you tell them? >> people will come here. their homes are already destroyed. they have nowhere to go. >> the israeli military said it has been targeted by fighters next to the schools. but children who once studied here and now live here, this is no longer safe, so they have to move and become homeless again. >> reporter: in total there are now almost 200,000 gazaens living in these schools, across 85 schools, and it's one in eight or one in nine of all people who live here. the u.n. said six of those schools have been hit by israeli strikes. >> nick schifrin for us. thank you very much. again, the israeli military saying they were responding to fire that was coming their way. in ukraine there are disturbing new claims that could prove deadly.

officials saying pro russian levels have planted landmines around crash site of malaysian flight mh-17. >> this is a brutal and dirty war. it's not being made out in the hills of ukraine but heavily populated areas. both sides have weaponry and they're not afraid of using them. the shelling close to where we are and killing civilians. separatists are accused of doing exactly the same thing. the ukrainians are trying to cut off any supply roots and in the meantime the most vulnerable people in elderly homes and orphanages are being evacuated from strongholds belonging to the straightists. separatists. they're trying to work out what

happened to malaysian airline mh-17, they're unable to get to that crash site and the heavy fighting and are in control of that area. the heavier the fighting becomes, the more difficult it will be for investigators to determine what brought the plane down. >> flying over war zones making people nervous boarding a plane. safety regulators say they're leaving it up to the airlines to decide where and where not to fly. one airline is criticized for its decision. >> the downing of mh-17 has put the spotlight on airlines and the routes they choose to fly. airlines that were flying over wester eastern ukraine immediately stopped. but what about iraq and syria. airlines are taking different positions with flying over iraq.

emirates said it will reroute around iraq rather than fly over it. but in a statement qantas said it wouldn't. >> there is no information to suggest there is risk to air flight flying over iraq. >> reporter: that has angered some, including those who represent qantas workers. >> at the moment you don't know you're traveling over a war zone. the companies don't tell you because it's cheaper to fly over the war zones rather than by pass it. >> reporter: would passengers pay more to avoid flying over troubled spots. >> i would spend more money rather than flying over a war zone. >> i definitely would pay more. definitely, to not take me over a war zone, yes. >> yes, i would spend more money. >> reporter: in canada the

international aviatio aviation discussed the airline crash. they didn't announce any immediate change at their advice. >> what we do need are authoritative, accurate, and consistent information and decisions from the authorities. we are only as good as the information with which we are provided. >> reporter: the meeting produced no blanket bans from flying over war zones. >> reporter: over there, the plane has taken off for dubai and it will fly over iraq. whether it should is a hot topic there. airlines the world over are facing similar dilemmas where their planes should fly. >> in india hundreds could be trapped under a mudslide. 17 bodies have been pulled from the mud.

it 457 after heavy rain. they have pulled out a few of the survivors but the thick mud and rain is hampering their search and rescue efforts. and in romania after being hit by surging floodwaters two people dead and hundreds forecasted to evacuate. the town got as much as ten feet of water. the french government has evacuated nearly french and british nationals from libya. the north african country has been unstable since it's up rising in 2011. dozens have been killed in clashes between rival militias. yesterday 30 people were killed. officials in nigeria say they're trying to find more than 30,000 people who may have been exposed to the deadly ebola virus. nigeria's first case surfaced in

legos. an american traveling to liberia collapsed at the airport and then died last friday. now those caring for ebola patients are dying themselves. dominick cane has more. >> reporter: this is another life lost to ebola. one of a growing number claimed by this deadlly virus. now the man in charge to stop it in sierra leone now has succumbed to it. he was praised for his national efforts to contain ebola but on tuesday it killed him. he was being treated in a hospital. the doctors and nurses there are the forefront of the battle against ebola. it's a battle they think they're losing. >> this is the first time i've treated an ebola epidemic of this size. there are hundreds of deaths.

we just can't control the epidemic. it's going in all directions, and we have few resources. >> reporter: what makes the problem worse in places is that some people fear wrongly that if they seek medical help they might not survive the treatment. >> they're frightened to say that they're ill. they're frightened to consult medical facilities to treat ebola or recognize ebola, it's one of the big challenges we're facing in responding to this outbreak. >> another growing concern for health experts and governments across west africa is a combination of a highly infectious, highly lethal virus, insufficient resources. already one of the biggest airlines in the region has stopped flights to sierra leone and liberia as a pre-sensitive measure because people who are incubating ebola are well enough to travel.

but when symptoms develop they expose their friends and relatives to the virus. medics and emergency crews seem to be particularly at risk. that is how two u.s. aid workers are believed to have contracted it. two of the men hundreds of people that this outbreak has now touched. it's already the worst ever recorded, and there is no sign that it's under control. dominick cane, al jazeera. >> an explosion at a college in nigeria has killed at least three people today, seven others were injured. police say a female suicide-bo suicide-bomber blew herself up outside of an administrative building. large amounts of students from checking their names on an admission list when the bomb went off. a man was charged with murder extradited from france yesterday and being held in prison in brussels. he's being interrogated, he led

sunni-led fighters. coming up on al jazeera america, from wall street to main street the president talks about the economy and congress.

>> there is good news on the economic front. 218,000 jobs were added to the private sector this month. that's down 63,000 from june but overall we're experiencing the fourth straight month of job growth. mcdonald's could be facing liability for claims that it's franchises mistreated workers. the company's corporate offices can now be named in complaints. in the past only franchisees have been held liable. thousands of mcdonald workers

have filed suit saying they were fired for participating in wage protests. updates on the economy from kansas city, missouri. people wrote the president about their struggles. we are live at the north lawn of the white house. what is the president's message today? >> reporter: that's right, dell, it's really a campaign with the atmosphere of using the bully pulpit of the presidency trying to get the american public on president obama's side. he talked about how he reads letters that americans season himself and staff picks him out to read. and the commander in chief received a letter thanking him for helping him for student loans. this is what he wants to see traction on even though he's being hammered by congress. he used this stop to push

congress to do more. >> we have the same priorities that ordinary families do. the same sense of urgency about the cost of college or the need for increases the minimum wage, how to make child care more affordable and early childhood education. if that's what they were thinking about we could help out a lot more families. a lot more people would be getting ahead. the economy would be doing better. >> reporter: now this comes as word has come from the commerce department that the economy grew in the second quarter by 4%, dell. >> so libby, congress, what is it work on this weekend? what still has to be done before they leave for the august recess? >> reporter: five-week reverse coming up in just a couple of days. of course president obama is pushing them on that front.

he's pointing out the fact that they are slated to leave town friday. >> i've only got a couple of years left, come on, let's get some work done. then you can go to the next president. look, we've got just today and tomorrow until congress leaves town for a month. we still have some serious work to do. we still got a chance to--we got to put people to work. >> reporter: you get the sense of the attitude that president obama is using, the tone that he's using, it's one that we've seen him while out and about. he is taking the message directly to the american people. what is congress doing? they did pass a route forward on the immigration bill, one that would deal with the border

issues and migrant children. the question is if it can get past the senate. even if it does, can the house move. they're looking at a package that would roll in money to fight wildfires out west and funding for israel's iron dome defense system. the house is working on something totally different. there is potential for them to leave washington without getting that dealt with. we're looking at a question of if they can get the v.a. bill passed. president obama pointed out that one vote the house is taking today, a vote to sue him. he said that is a waste of time, but house speaker john boehner pushed back and said the republicans are working on jobs and the economy. there is heated discussion before the town quiets down. >> congress will be leaving in august.

lib lib joining us from the white house. thank you very much. coming up on al jazeera america.

over the last 24 hours. the figh fighting stops the investigation of the crash site of malaysian flight mh-17. well, performing on a broadway stage is something that actors and actresses dream of, but it can rick their health. she'll mcvicker has the report. >> i started doing theater when i was in third grade. going from a small town where i was known for my ability to new york city where it was really scary and everyone was phenomenally talented. >> reporter: when kimberly moved to manhattan from new jersey to pursue that show business dream the odds were already heavily stacked against her. >> i'm going to have to work really, really hard and i still might not make it.

that's really terrifying. >> reporter: then she suffered a devastating vocal injure, one that is increasingly common among today's singers. >> i would lose my voice and i would feel so anxious. that's the first time i felt, am i actually really going to be able to do it. [♪ singing ] >> the injury exists in every genre of music. >> reporter: david mills is one of new york's most renown vocal instructors. >> on stage all of a sudden these shows are being written where the female voices have to go much higher. >> reporter: until recently broadway leading ladies were sopranos like shirley jones. shown here in "oklahoma." in the past decade big time belters have come into favor. the notes are higher and require

more vocal heft. >> reporter: broadway singing breaks down in two categories. >> the julie andrews sound. and the contemporary belt like patty labelle. it has to increase air pressure. so the increase of air pressure pushing on the vocal cords and the resistence, and they have to resist more and more and it's like going to the gym and trying to pick up 300 pounds. you're going to sprain something. >> these are high level athletes. >> reporter: treating broadway's renown performers. >> to expect to perform at that level day in and day out each day of the week is frankly

ridiculous. >> reporter: they conducted the first-ever study of vocal health of broadway singers. the results, over 25% of performers had a diagnosed vocal injury. kimberly townsend is working through her injury. she exercises her voice for hours each day. >> three hours every day for sure and sometimes a lot more. i do vocal range work. i do warm ups. i know that i still have that talent, but it's raw, and it needs to be refined again and shaped again. >> reporter: as broadway faces for another billion dollars dollar year singers like kimberly townsend are putting it all on the line. sheila mcvicker, al jazeera. >> authorities have a massive clean up job after a broken watermain spilling 8 to 10 million gallons of water into the surrounding neighborhood. authorities were not able to

shut the water off until three hours after the main broke. people had to be rescued. the loss of water comes as california deals with that drought. they are making progress on the wildfires. yosemite national park still in jeopardy. how big is the concern for the park and the neighborhood surrounding it. >> reporter: for the neighborhood surrounding it, it has pushed away from that, but it's moving north to the park to where there are the giant sequoia trees. it is just south of that grove. the temperatures are heating up, so it's not making the best situation there. no rain predicted in the highs that will go 100 degrees again today. the heat is really a wig problem there. you can you can see the fire spreading to the north in that mountainous terrain. they're trying to get a handle on it, but still the temperatures are a big problem there. you can see that the temperatures today are in the 60s in san francisco, but

that's that cooler air. highs will go to close to 100 degrees again and the heat warning is in effect with phoenix in 101. that could climb to 110 and 115 today. maybe a few light showers but not much predicted in the way of rain. there is that red flag warning for some rain here in nevada. but not really over the areas where they need the rain especially dealing with that fire now. here is the excessive heat warning across the southwest. the temperatures crime to 115-115. the area of rain over kansas ex-oklahoma, and texas, adding cooler air there. and cooler temperatures across the southeast. very unusual to see low temperatures like this around atlanta. and 66 degrees and lower humidity. so there will be a nice break. but for now the sequoias are safe. >> meteorologist: they are safe, yes. >> we want to thank you for
