this is the "cbs evening news." >> good evening. i'm jim axlerod. the libyan man snatched near benghazi and suspected in the consulate that killed four americans, including ambassador chris steven, is now on american soil. under heavy security in washington, d.c., ahmed abu khatalla made hits -- his first appearance in federal court this afternoon and pleaded not guilty to charge of conspiracy to provide support to terrorists. for the last two weeks, khatalla had been held and interrogated on navy ship before being flown by helicopter into washington this morning. mark albert begins our coverage. >> reporter: the entire hearing took just ten minutes in a heavily guarded courthouse blocks from the capitol. flanked by u.s. marshals, khatalla appeared in federal court in dark hooded sweatshirt and dark pants. he was not visibly restrained and raised his right hand to take the oath. through an interpreter, khatalla said he understood the charge against him, a one-count

indictment of conspiring to provide support to terrorists. khatalla's appointed attorney entered a not guilty plea on his behalf. other charges will likely be added later, part of a government strategy to keep sensitive information under wrap in the a public criminal trial. the justice department describes khatalla as one of the key leaders behind the assault on the american diplomatic compound in benghazi. khatalla had appeared frequently in public since the attacks on september 11, 2012. just one month later he spoke with cbs news off camera at a benghazi hotel where he sipped mango juice and dared authorities to come after him. on friday, pentagon spokesman john kirby said the u.s. did just that. >> he's not sipping mango juice anymore in a cafeé in benghazi. he's on his way to court. that's what's really important. >> reporter: and khatalla was brought here to the federal court in d.c. he was questioned for a week before he was arrested. his next court appearance is a

detention hearing on july 2nd. until then the u.s. marshal service says it is holding him at a detention facility somewhere in the d.c. area. jim? >> mark, thank you. let's bring in our senior national security analyst, juan zarate. juan, interrogators have had khatalla for two weeks while they transported him here. we're told at some point in the process he was read his rights. what kind of information are interrogators looking for? >> intergaitors are interested about any plots or threats to the west, any information about operatives coming from the west and any information that khatalla may have had about operations, communications with terrorist group, not just in libya but in the region. they would then, of course, have been interested in information about the benghazi attack. based on the information i know, he was talking both before he was read his rights and after. >> from what you know, do you expect to see more arrests in this case? >> i think authorities are certainly looking at other operatives and potential defendants in this case.

they're going to take their time, though to, both perfect the case and to find the right target of opportunity. those associated with khatalla have watched very carefully what happened to him and have seen now two operations in libya. so they're going to be hunkering down, and given the chaos in that country, f.b.i. and special forces will take their time to find the right opportunity. >> juan zarate in washington, thank you. >> thank you, jim. >> after weeks of retreat, iraqi troops are unlearning an air and ground assault on sunni militants in the northern city of tikrit, hoping to retake it from them. as charlie d'agata reports, the fighting has been fierce in iraq and government claims of progress are being contested by some foreign workers caught in the crier. >> reporter: iraqi forces have been pushing north to take control of key cities that had fallen with lightning speed to isis militants. military officials today said commandos backed with tanks and helicopter gunships had been deployed to take on sunni insurgents in tikrit, saddam

hussein's former hometown. driving militants out of tikrit would give the iraqi military a strategic hold of a major northern city and would boost morale to a force that has so far been unable to stop isis. it also helps cut off one of the major routes to the capital. just 35 miles south of tikrit and on the road to baghdad is the contested city of samarra, which today iraq's military spokesman insisted is under complete government control. but these chinese construction workers, who are trapped in the fighting in samarra and later evacuated to baghdad, tell a different story. they said they had to be rescued by iraqi forces over the course of two days. kimi duan is one of the men who helped evacuate 1,200 of his colleagues who were building a power plant in the city. as you were leaving, did it feel like that area was under control of the iraqi army? >> i think it's... you can see the army, but we see they're not

100% ready to take back the city. >> reporter: they've been arriving by the busload. this has been turned into a holding area. they say the fighting got so intense in samarra they feared for their lives, and now all they want to do is go home. ramond chenrun is a translator with the evacuees. >> you cannot imagine the feeling that we come here. when i come here, i see the chinese army. i was very happy about that. >> reporter: a joint u.s.-iraqi operations command center has been set up here in baghdad. it's unclear what kind of u.s. involvement went into the planning of this offensive to the north, but iraqi military spokesmen said today that the coordination is at the beginning stages. jim? >> charlie d'agata in baghdad for us tonight reporting on the fluid situation in iraq. charlie, thank you. house minority leader nancy pelosi was in texas today visiting a detention center where migrant children are being held. pelosi was briefed on the

situation, but she did not meet the children. she did tell reporters she's not hopeful about comprehensive immigration reform this year. children at the facility did get another high-profile visitor, the first lady of honduras. many of the children being held at the facility are from honduras and were fleeing violence there. vicente arenas spoke with the first lady. >> reporter: these photos obtained by cbs news show the conditions inside border detention centers across texas, rooms jammed with children, families and young men. this year the number of minors crossing the border illegally has almost doubled from last year. the majority of the people are children. that's why the first lady of honduras came to this station. she meat five-year-old boy in tears. "the boy didn't know the town he

came from," she told us. "i did my best to comfort him." >> they're telling you they're coming because they can come and stay here. >> exactly. >> reporter: in 2009, fewer than 1,000 honduran children came to the united states illegally. this year that number is more than 15,000. many of these immigrants are being held in congressman henry cuellar's texas district. he wants illegal immigrants from central america to be deported quickly and not kept here indefinitely. >> mexicans within 48 hours are pretty much returned, but the kids and other folks from other countries are put in a different system. why can we not treat everybody the same? >> reporter: the illegal immigrants keep coming. a source tells me on one night earlier this week, nearly 400 were caught along the rio grande here, many of them unaccompanied might beers. on monday department of homeland security secretary jay johnson will come to texas to check on facilities housing children. vicente arenas, cbs news, mission, texas. >> so far it's been the reddest

june on record in parts of the upper midwest, and this weekend is only going to see more rain. lauren casey of wcco in minneapolis joins us. lauren, a rather large and powerful storm in the midwest. who exactly is in its path? >> reporter: the storm system features very strong winds in the mid-levels of the atmosphere, and it's producing the threat of large-scale wind damage event across the nation's mid-section from northern minnesota stretching as far south as southern oklahoma. this evening and tonight. the widespread downing of trees and powerlines is likely in states affected by these storms. the threatary narrows but elevates tomorrow with the increased risk of a tornado and a moderate risk area which includes much of iowa and nebraska. large hail is also possible during this multi-day severe weather event, which will extend into monday when major midwest cities such as chicago, indianapolis and kansas city will contend with these severe storms. >> it looks like wind and even
