Axelrod teri okita with this heartbreaking story. Ter, thank you. Cruise ships a continent apart are dealing with the same problem tonight.

Axelrod ukraines acting president called an Emergency National security meeting today after armed prorussian militants seized government buildings in several cities in eastern crook. Katie stallard is in donetsk. Katy, what are the militants demanding . Reporter theyre demanding a referendum on federalization, which would effectively mean the creation of an independent state within the state of ukraine. Some of them want to go further. They want to break away from ukraine altogether and join russia, and tonight in donetsk, the city where i am, they claim that the police are with them, that they are standing behind the protesters here, and similarly, a small town which came under attack by armed masked men in combat fatigues this morning, they say they are holding two key buildings in that town, and with Russian Forces continuing to mass on the borders here, there are real fears this could be the next domino in this situation to. Axelrod so let me follow up on the fears this could be another crimea. How legitimate are those fears . Reporter well, the parallels are very striking. What you had there were armed masked mensing key strategic buildings. Then a referendum, which became a question on joining the russian federation. And we know how that ended up. So there are real fears here that this could be another crimean scenario as the government in kiev are pushing it. They are conveeng a meeting of the National Security council to try to deal with this, but the situation they are facing here in the east is very serious and very real, indeed. Reporter Katie Stallard reporting for us tonight from eastern ukraine. Thank you. Late today, the white house announced Vice President joe biden will be traveling to kiev, the ukrainian capital, later this month in a show of support for the ukrainian government. Severe weather in this country is slamming the midwest tonight. Powerful thunderstorms plowed through grand rapids, michigan, with winds approaching 85 miles per hour. The National Weather system called it an extremely dangerous situation. Heavy rain could cause flooding in the midwest tomorrow. The federal government is now stopped rounding up cablgths grazing on Government Land north of las vegas. Cliveen bundys family owes more than 1 million in grazing fees. The family scuffled with officers when they started to round up the cattle last week. Armed protesters then showed up to support the bundies so the roundup is on hold for now.

Lets go, boston axelrod they came from all corners of the city, survivors, first responders, politicians, and well wishers. They all gathered today on bostons boylston street as the anniversary approaches of the bombing that tore a hole through the city of boston and the nation as well. They gathered to show their strength. Ready, folks . Reporter the Sports Illustrated cover shoot was held at the marathon finish line where hundreds had gathered last april 15 to cheer on the runners. It was just before 3 00 p. M.

Really, it shows you how strong we are as a city and how much were actually feeding off of the survivors. cheers axelrod a million people, twice the usual number, are expected to gather along the route this year to cheer the runners on. Up next, the latest on protecting yourself from bleerk an Internet Security threat when the cbs evening news continues. Axelrod reports about the socalled bly bug have rattled many intirnltd use. Its the name of a flaw in a Security System that could put credit card numbers and pass words at risk. Reporter any web site with this little pad lock uses a Security Program called open ssl. It protects twothird of the internet. This week, researchers realize its been vulnerable to hackers for close to two years because of a hole in the software. When you log on to one of those web sites, your computer communicates with the sites server on a secure, encrypted line. Its like a pulse constantly identifying your identity. What bly does is allow a hacker to break in and hunt around for your information, like user names and pass word. A server cant tell the difference between you and the hacker so the hacker gets anything you have written on that web site and disappears without a trace. Theyre basically looking over your shoulder and witnessing all the information youre giving. Reporter Alyssa Bereznak is a columnist for yahoo tech. How do you fix it if it affects twothird of all web sites. Users need to replace their password because during this twoyear span they could have been eaves dropped on or an attacker could have seen their login information because the software was vulnerable to attacks. Reporter its not clear how much information, if any, has been compromised, but major web sites like instagram, facebook, and google say they detected the flaw and have now fixed it. What was stolen is unknown. Thats the scary thing about this is how much we dont be, and theres no way of being able to track this because it existed for two years heartbleed could be one of the biggest holes in the internets history because every user was vulnerable and no one even knew it existed. Vinita nair, cbs news, new york. Axelrod some questions as we look ahead to tax day. Who cheat and why . Odonnell axelrod just in case youve lost complete track of the calendar, we have a reminder tuesday is the deadline to file your income tax returns. The i. R. S. Estimates 270 billion in revenue will be lost due to unreported income, this despite polls showing 90 of americans think cheating on taxes is wrong. Our Business AnalystJill Schlesinger joins us. The numbers dont seem to square. Who is cheating . According to the i. R. S. It is the Small Business owners who are underreporting their income by 43 , a big number. Now, i dont want to suggest Small Business owners are bad guys and gals. Its just that they have an opportunity to report. Remember, most of us are w2 employees. Our companies are reporting what we make to the i. R. S. We dont have a chance at doing it. But even in these small areas, tbhoaks have baby sitters or nannies, 90 of them are cheating on their taxes, just suggesting that perhaps were not quite as against cheating as we say we are. Axelrod it seems to be a 87 opportunity. The i. R. S. Also talks about something called the chump factor in explaining cheating. What is that . Reporter the i. R. S. Found in a survey 73 of americans think that other wealthier americans are using tax loopholes that they dont get. So imagine if you think someone else is getting something, you tonight want to feel like a tax chump. You want to feel like you are exploiting the code to the best of your ability. Of course, that can lead you to do some really dump things. When i was a Financial Planner for 14 years what, tended to happen is people would cheat on dumb, Little Things with such a big risk of an audit looming ahead of them, it seems crazy. Axelrod let me ask you about this other story going around is the i. R. S. Actually going after the Adult Children of dead people because the i. R. S. Thinks those dead people owe backtaxes . Reporter well, there is some confusion. It is an i. R. S. Social security problem but, yes, what seems to be happening is the government is saying if your parents got paid too much money maybe it was a tax refund, maybe too much in Social Security they can come back and take a portion of your tax refund to make up for your parents generation. This is crazymaking, and is sort of impossible to fight it. Only 10 of the folks trying to get that money released back to them are successful. They often have to hire eye lawyer to do it. So i think this is why senators Barbara Mikulski and Barbara Boxer are looking into it and saying this doesnt sound right. Axelrod and some legal challenges already under way. Well see how those turn out. Jill schlesinger, thank you. Thank you. Axelrod its one thing to get touched by an ankle but touched by a fan seemed to upset an outfielder. Curtis granderson caught a ball and was tapped on the back by a fan. He thought it crossed the line. They exchanged words and the fan was eject from the stadium. Just ahead, take a look at this 120 million home and that is a markdown. Clb Prince William and kate, the duchess of cambridge, and baby Prince George continued their royal tour. Nearly 10,000 people greeted the couple. They laid flowers at a war memorial and the duchess of cambridge visited a childrens hospice. When it comes to location, location, location, theres no more valuable location than greenwich, connecticut or at least thats the location of whats believed to be the most expensive private home ever sold in the United States. The 13,000 square foot mansion sits on 50 acres of waterfront property and comes with a pool, tennis court, and two islands. This all went for 120 million, which may actually be a bit of a bargain because that is 70 million below asking. An extremely rare easter egg, and now pretty good nest egg, goes on display in london on monday. Its a golden fab jay easter egg worth about 33 million. A midwest scrap metal dealer bought it at a flea market for 14,000. He planned to sell it for scrap before founding out it was a lost piece of historic art. And it was a Beautiful Day for a parade in washington, d. C. , which is exactly what they had planned there. The National Cherry blossom festival parade, after a brutal winter, it is especially nice to see the blossoms in full bloom. And our own Norah Odonnell was one of the parades cohosts. Coming up, the height of artistry deep beneath new york city. Axelrod weclose tonight with a story about sightseeing in new york city. It turns out it doesnt always involve looking up. As jill wagner shows us, in at least one case, its all about looking down. Reporter one of the great architectural treasures of new york city is underneath this plaza. The Old City Hall subway station, shuttered for 70 years and left to collect dust in the dark, even with its majestic arches and shand leers that rival any cathedral. When it opened it was called the mona lisa of subway stations. Reporter it was one of many structures built by the guastavino family, now being celebrated in a wonderous exhibit at the museum of the city of new york palaces for the people. John ochsendorf is a professor at the Massachusetts Institute of technology and curator of the exhibit. Hes dazzled by the marriage of beaut and function in guastavinos work. This particular staircase goes up for about 10 stories. This is absolutely aweinspiring as a work of technol but also as a work of art. You know, im an engineer, but i struggle to explain how this stands up. Reporter the guastavinos were spanish immigrants who brought centuriesold mediterranean techniques to the United States in the late 1800s. They used the technique called thintile vaulting to create a signature and patented style. It was inexpensive, light weight, and strong. The mortar would set enough to hold the weight of a single tile. Reporter in all, their domes, arches, and Vaulted Ceilings grace more than 250 buildings in the new york city, like the ellis island registry room, and theica hederal of st. John the divine in harlem. If anyone finds a guastavino billion i do not know about, i will buy you lunch. John ochsendorf has been on a safenger hunt for these sites for years, and today the realization of a lifelong dream i have a dream some day it could be reopened either as a station or a museum. Reporter he traveled by train for a private tour of this underground treasure, hidden for decades in the heart of new york city. Jill wagner, cbs news, new york. Axelrod gorgeous. And thats the cbs evening news for tonight. Later on cbs, two editions of 48 hours. For now, im jim axelrod in new york. For all of us here at cbs news, thanks for joining us and good night.
