good evening. the already strained relationship between the u.s. and its wartime ally, pakistan, has been further stretched toward the breaking point after a nato air an attack killed 24 pakistani soldiers. it happened this morning in a pair of border outpost-s. details remain murky. notably washington has not directly accepted blame. tonight pakistani officials are calling the incident a grave infringement of the country's sovereignty and have moved to cut off critical support to the neighboring war effort in neighboring afghanistan. >> reporter: good evening, lester. today's attack was not only a tremendous loss for pakistan's military, it was perhaps the most damaging incident for u.s.-pakistani relations in years. pakistan responded quickly today, closing its two border crossings into afghanistan,

cutting off the main supply routes for u.s. and nato forces within hours of the nato attack. nato aircrafts were apparently responding to enemy fire from a volatile and sometimes undefined border. >> support was called in in the development of a tactical situation. it is what highly likely caused pakistani casualties. >> reporter: at least two pakistani troops were killed in a military post at the border. pakistan's government called the attack, unprovoked, indiscriminate and intolerable >> translator: today at 2:00 in the morning there was an attack on pakistan. an attack on pakistan's solidarity and independence. >> reporter: in addition to closing the border crossings, the government ordered the united states to vacate an air base in northern pakistan that reportedly uses to launch cia drone operations. even before today's attack, there were deep strains in u.s.-pakistani relations. in may, when u.s. forces crossed into pakistan and killed osama

bin laden, the government was furious because it had not been told of the operation. last year, pakistan closed one of its border crossings for about ten days. when u.s. helicopters accidentally killed two pakistani soldrs, the u.s. then apologized. today's incident comes just one day after marine general john allen, the commander of nato forces in afghanistan, met with the head of pakistan's army to improve coordination among u.s.-afghan and pakistani forces. >> we look at it from a strategic standpoint. why can't we identify pakistanis across the border and not bomb them? but for the guy on the ground if somebody's trying to kill you, you're going to try to kill him back. >> reporter: and recent months afghan officials have also asked for better coordination among the forces along the border because of pakistani rockets being fired into afghanistan killing civilians. pakistan claims that they were fired at insurgents and not

civilians. lester? >> thank you. and with its relationship with pakistan already on the rocks, the white house is choosing its words about this carefully. kristen welker is on the north lawn. kristen, what's the administration saying? >> reporter: good evening, lester. the white house is being quite measured in its response, in part because white house officials don't have all of the facts right now. and also because the u.s. relationship with pakistan is so incredibly complicated. here's what white house officials had to say earlier today in a statement that we have saying "senior u.s. civilian and military officials have been in touch with their pakistani counterparts from islamabad, kabul and washington to express our condolences, our desire to work together to determine what took place, and our commitment to the u.s.-pakistan partnership". now still some analysts say that this whole incident might put is back to square one, back to the days right after osama bin laden was killed. now, secretary of state hillary clinton visited pakistan last month and urged top officials there to get tough on militants.

some analysts believe this latest incident could undo any gains that were made during that visit. now, analysts watching this quite closely in fact one telling me that this could be a "catastrophic blow to the u.s. relationship with pakistan" although another expert warns it is still very early and might be too early to know what the full impact of this will be. lester? >> kristen, thank you. another hot spot overseas remains egypt where today violent clashes continued as military rulers try to negotiate an end to an increasingly deadly standoff. for the latest we turn to nbc's iman mohadin in cairo. good evening. >> reporter: good evening, lester. it was the prime minister's first day on the job and one that began with tragedy. outside the cabinet office where he was going to assume his responsibilities there was a protest there physically trying to prevent him from entering the building. in the ensuing confrontation, a protester was shot by a security vehicle and he was killed

instantly. now, the general prosecutor's office has launched an investigation into the incident, vowing to hold accountable anyone responsible. but the protesters felt the attack was deliberate. they've seen these types of attacks on the protesters in the past. it gives you legally a senreall the tension between the two sides. this during negotiations taking place between the military and key protest figures. they've demanding the military step down from power and hand over control to a civilian government. but the civilian government has not been successful in receiving power. they say it may be several months away before power is ready to be handed over to the people. >> thank you. one more note overseas tonight in the wake of this year's arab spring, ahead of a predicted islamist victory in egyptian elections, an islamist

party is poised to take power in more morocco. it becomes a second country after tunisia to launch a pro dempsey government. shoppers and retailers alike welcome some beautiful weather over much of the nation today as the opening weekend of the holiday shopping season continued. new figures out tonight indicate a strong start. sales up more than 6% over last year. buyers spent $11.4 billion on black friday. that's up nearly $1 billion from a year ago. we get more now from abc's john yang. >> reporter: across the country, the weekend shopping spree continues full force. at a washington bookstore, the first family got into the act. early numbers show shopping's been particularly strong online. according to idm core metrics, black friday internet buying jumped nearly 25% over last year, and a whopping 39% on

thanksgiving day. >> it's getting bigger and bigger and bigger every year. about $60 billion is actually going to be transacted online this year. >> reporter: analysts say it's driven by the search for the best possible deals. >> i'm going to be spending less because we just don't know what the future holds. >> once i reach my limit, that's it. so everything's on a budget. >> reporter: but not everyone's feeling the pinch. analysts say the affluent are looking for the highest quality possible and the latest most innovative products. >> we've we're seeing higher tickets being sold. they may not buy as much but they're buying the items that are the most expensive. at the low end it is all about the price. the deals that are out there, they're extensive and they're coming at all different times. >> i wish you guys had layaway. >> reporter: layaway is one way retailers like walmart are trying to appeal to budget-conscious shoppers. it allows them to make small payment over time before getting the product. this woman is trying its for the first time. >> it was a good deal.

if we could pay for it slowly why not? >> reporter: financial experts say it could help consumers with bad credit but urge them to read the fine print because it can end up being more expensive than using a credit card. and there are other potential pitfalls, too. >> there are some retailers that if you make three or four payments and decide you don't want the product you won't be able to get a refund and you're out the products. >> reporter: it's a risk some are willing to taken to sure a merry christmas even amid a gloomy economy. john yang, nbc news, new york. new york senator chuck shul schumer and americans for tax reform david norcrist willing the guests tomorrow on "meet the press". news of handshake deal to end the nearly 5-month-old nba lockout and put players back on the court by christmas. more now from nbc's mark potter. >> reporter: once again, it appears to be game on. after a lockout, lawsuits and bitter negotiations, the wee

morning hours brought news of a tentative deal pending ratification by nba players and owners. >> we're optimistic that that will all come to pass and that nba season will begin on december 25th, christmas day, with a triple header. >> reporter: if as expected the agreement is approved and those three games are played, the nba will have averted a major disaster. >> i think both sides realized that this was the 12th hour. it wasn't the 11th hour. this was the time that they had to do a deal. and if they didn't do a deal, they would lose the season. >> reporter: this year's season will be shortened from the traditional 82 games to 66. but fans are thrilled the game has been saved. >> i was so excited that we finally got to watch basketball again. >> i love this game. like that's my favorite thing to watch. >> reporter: among them the nation's first fan, president obama.

under the proposed ten-year agreement, players reportedly gave back several billion dollars in game revenues to team owners. >> i think the players are agreeing to it because they're missing paychecks. they just missed their first paycheck on november 15th. >> reporter: here in miami where it's high dollar players and many hotels, restaurants and businesses fearing huge losses if games aren't played, there was a big sigh of relief now. on his twitter feed, miami heat star lebron james said "i feel like my kids on christmas day. so juiced. excited for the fans that stayed patient with us". nba owners and players hope that by finally coming to terms now they'll keep those fans filling the stands. mark potter, nbc news, miami. the folks at nasa are calling it the monster truck of mars. and tonight the world's biggest extraterrestrial explorer is on its way to the red planet. for nasa this new mission in search of life carries high hopes and high risks. nbc's tom costello has our report. >> 5, 4, 3, 2, 1.

>> reporter: with the saturn five liftoff at the kennedy space center, nasa has launched its most sophisticated and ambition mission to mars yet. just traveling the 154 million miles to the red planet will take more than eight months. then next august a high-risk landing as a supersonic parachute slows the science lab's descent to mars, 60 feet above the planet a sky crane will gently lower the rover naped curiosity onto the martial surface, leaving the rover on its own to look for signs of life, past or present. >> do we anticipate that we'll learn a whole lot about mars? absolutely. do we know what specifically that will be? no clue. >> reporter: curiosity is a six-wheeled rover standing more than six feet tall, able to drive long distances under an martian sun, analyzing rock and soil samples and sending the results back to earth.

nasa has carefully selected the landing zone on mars in the gael crater where a huge mountain rises right out of the crater floor. scientists believe they see layers of sedimentary deposit here that they hope will help them understand more about mars' history but alsoless wh what ha to the lakes and rivers. >> reporter: the evidence this scientist says now seems clear that mars once had a very warm environment. >> perhaps even today. >> reporter: that possibility poses a big problem. nasa has gone to great lengths to ensure curiosity doesn't carry any earth germs that could contaminate life on mars. high resolution cameras have already detected what appear to be large ice sheets buried under the martian surface. curiosity's mission to determine whether life is or ever was buried there, too. tom costello, nbc news, washington.
