good evening. the heavily armed militants fighting their way across iraq known until now as isis are no longer a matter of concern just in that region. there are now real concerns they could hit u.s. interests here or abroad. and in iraq, there's renewed concern about protecting the u.s. embassy, a gleaming symbol of the united states, which could be a large and inviting target. just tonight, the white house has announced its intention to send 300 more military personnel to iraq along with drones and helicopters for, quote, intelligence, surveillance and reconnaissance support. we begin tonight in baghdad once again with our chief correspondent richard engle. richard, good evening. >> reporter: good evening, brian. the u.s. sent these additional 300 troop, not just to protect the embassy and assist in a possible evacuation, if one were ordered. no evacuation of the embassy has been ordered, but also to

protect the baghdad international airport. militants in isis have positions not very far from the airport. they also have captured artillery which would potentially allow them to attack the airport from afar. all of this is a sign how seriously the u.s. is taking the threat from isis, not just to iraq or the region, but directly to the united states. isis militants have land, weapon, and ambition. and u.s. officials are now very worried. several counterterrorism officials tell nbc news the threat from isis to american interests is, quote, extremely high. they say isis is developing advanced bomb making skills. and cultivating a roster of foreign suicide bombers who could target the u.s. and europe and they're bragging about it. this fighter claiming to be from chile says iraq and syria are just the beginning.

>> iraq, jordan. >> reporter: isis puts out daily propagan propaganda, videos showing its brutal attacks. the videos can't be independently verified, but the intentions are clear. >> we are going for you, barack obama. >> the holy grail for these groups are to strike in the west. attacks in london, attacks in the united states. this is what they strive for and more and more, this is a concern of u.s. intelligence. >> reporter: there is one saving grace -- isis, savage and intolerant, is generally losing support wherever it goes. in a baghdad mosque today, iraqi shiites expressed disdain for the group. they are hated, and in sunnis agree.

by being so bold, perhaps overconfident, isis has created a lot of enemies. you have to be uniquely unpopular to the hezbollah, israel, the syrian rebels, the u.s., russia and iran all ending up against you. but hated or not, isis has carved out a safe haven in the heart of the middle east that may now be the most dangerous terrorist sanctuary in the world. u.s. officials say about 70 americans have also traveled at some stage to fight in syria and that about a dozen are there right now. u.s. officials are also very concerned about the hundreds of fighters with european passports which could potentially make it easier for them to make it into the united states and carry out some sort of attack. >> richard engle starting us off again tonight from baghdad. richard, thank you. elsewhere in the middle east today, the bodies of three israeli teenage boys were found near the west bank town of hebron where they were abducted

while hitchhikes two weeks ago. president obama was among those who expressed outrage over the killings. the abjusts were praised by the palestinian group hamas. and after the bodies were discovered the israeli prime minister benjamin netanyahu declared that, quote, hamas will pay. big day at the supreme court on this last day of its term. they ruled that, like the rest of us, corporations have a right to exercise their religion. in this case, where it applies to providing insurance coverage for contraceptives. but the court emphasized this doesn't mean companies are free to use the ruling to ignore any law they choose. our report from justice correspondent pete williams. >> reporter: supporters of the hobby lobby cheered today's victory. the oklahoma family that owns the chain of 500 craft stores claimed that providing insurance coverage for some points of con that septemberives under obama care would be the equivalent of paying for abortion, violating the company's religious beliefs. by a vote of 5-4, the court said

a profit-making company can have legally protected religious freedom, ruling the owners of hobby lobby and a pennsylvania cabinet maker don't forfeit protection for their religious reviews when they incorporate. >> we are truly thankful for this decision that allows us to continue operating our family business according to principles. >> women who work for these companies can get contraception coverage under another way under obama care. either the insurance companies or the government pays for it. women's groups say the court was too worried about the rights of the companies at the expense of their employees. >> it's the individual religious beliefs of the woman should matter. her boss shouldn't decide for her. >> some called the ruling startling. the court's majority said big publicly traded companies cannot claim religious objections, only

what it called closely held companies organized around clear religious views like the greens who own hobby lobby. but could the ruling allow some businesses to refuse to hire or serve people based on religious grounds? >> the justices signaled those claims would lose because here the government had another way out, but they don't have another way of preventing discrimination. >> reporter: the obama administration today said congress may have to fix what the court has done. >> today's decision jeopardized the health of women employed by these companies. >> reporter: a wall street journal fol in march found 53% of companies should not be exempt on religious grounds from providing birth control coverage. house speaker john banener a written statement says the ruling proves president obama overreached in the health care law. but house democratic leader nancy pelosi said women should not be forced to jump through extra hoops to get the health coverage they need. the court today also dealt something of a setback to labor

unions that represent government employees. today's ruling does not apply to full-time public employees to teachers, fighters and police. but government workers who care for people at home and don't join a union do no the have opay union fees. opponents oof public sector union hoped the court would go further. still, another 5-4 vote does chip away at the power of public sector unions. brian? >> pete williams after a busy final day this term at the supreme court. pete, thanks. as thousands of undocumented immigrants cross the border into this country, many of them children, the president said today he'll no longer wait for congress to act on broad immigration reform. he announced his intention to move on his own starting with an action to make it easier to deport people who cross the border. >> i take executive action only when we have a serious problem, a serious issue and congress chooses to do nothing.

and in this situation, the failure of house republicans to pass a darn bill is bad for our security, it's bad for our economy, and it's bad for our future. >> and along our southern border today, the humanitarian crisis was only getting worse at what one congressman is calling refugee camps. we have more on that tonight from nbc's miguel almaguer. >> reporter: this is what an immigration crisis looks like. waves of children risking their lives. today along the texas border, the influx continues. since october, 52,000 children, many traveling alone to escape poverty and violence in central america have been apprehended trying to enter the u.s. those of you thinking oof sending your children on the long 1,000-mile journey need to know it is not safe. it is dangerous. it is dangerous.

>> reporter: detention centers along the border are overwhelmed. not enough beds or blankets to go around. many who work with undocumented immigrants say this crisis is a wake-up call. >> this issue, since it involves children, could be the rosa parks moment of immigration reform. people are going to be saying my god, how about my children? how about if i was in that situation? >> 100 miles from the border in california, tonight, the locals say they are bracing for but cannot handle an onslaught of immigrants. >> we're not prepared for this type of influx. we weren't prepared and we're not prepared. >> with the border patrol facility just outside of town, 140 children and adults are scheduled to arrive tomorrow. the mayor said this is just the first wave. many more will come. >> the true solution to this

will be a clap tollaborative ef sending a message to washington, d.c. to put a stop to it so we can stop managing their headache. >> undocumented immigrants will come here every three days. many will be released right into local communities. brian? >> miguel almaguer, thanks. for the middle part of our country, no let-up tonight of a wave of severe and dangerous weather. a lot of it hitting in iowa today, and now heading east. we get our report tonight from nbc's katy tur. >> reporter: a relentless series of storms battering the midwest today. 50-foot trees, no match for powerful winds just north of des moines. outside cedar rapids, a sinkhole on highway 1 that swallowed an suv. and golf ball sized hail pounded fort dodge.

thunderstorms left this family home smoking after a lightning strike ripped open their roof and rushed them out of bed. >> we heard the sirens go off. a thunder boom shook the whole house. in minnesota, a weekend rain kept the mississippi above major flood stage. this june is the wettest on record since 1874. >> stay on this side of the street. don't go this way. >> reporter: security footage caught the power of an ef-1 tornado in wisconsin. and downed trees blocked streets. >> i have never felt that feeling of standing in the house and all of a sudden it seemed like the roof was going to lift right off the house. >> reporter: meanwhile in memphis, tennessee, roads became rivers, and storms lit up the sky. and tonight, millions more are still under threat. these storms are already being blamed for one death in iowa. and the national weather service just issued a particularly dangerous situation for chicago

as wind gusts of 80 miles an hour is headed this way. >> katy tur in chicago, thanks. >> with we're keeping an eye on low pressure east of florida that could become a named tropical storm. that would put it near the outer banks by the fourth, before it would depart up the coast on towards new england. gm announced yet another recall today. this time more than 8 million cars, mainly older and mid sized models. gm said the issue in this one is, quote, unintended ignition key rotation. this brings total gm recalls for the year to nearly 29 million, and that's a record for any carmaker ever. also today, the attorney kenneth feinberg announced plans to pay victims of crashes involving those defective gm defective ignition switches. we know of at least 13 deaths. each family will receive at least $1 million. feinberg has had the same role,
