The president ial palace just around the corner. This man was in a nearby building. I was trapped, he said. People were on the floor, and there were streams of blood. The taliban has denied responsibility. Afghan intelligence suspect the militant network in the east of the country may be to blame. The attack comes at a time the u. S. Is weighing sending in more troops. Just as the militants proved yet again they can strike at the heart of the city. This attack may lend more weight to those who argue that the u. S. Should be sending thousands more troops to afghanistan, but after 16 years of war, the cost of over 3 billion a month, its not a clearcut desis at all. All right, thank you very much.

From the Broadcast Center in new york city, im jeff glor. This is the cbs overnight news. Welcome to the overnight news. Im michelle miller. A turning point in the investigation of russian influence on the president ial election could come next week when fired fbi director James Comey Testifies on capitol hill. Comey is expected to confirm reports that President Trump asked for his loyalty and pressured him to close the Justice Department probe. Jeff pegues reports. Reporter sources tell cbs news that special Counsel Robert Mueller has given his blessing for former fbi director james comey to testify before congress. Comey is expected to discuss memos he wrote about meetings with President Trump, including one in which comey says the president asked him to drop his investigation of fired National Security adviser michael flynn. According to the memo, the president said of the private meeting, i hope you can see your way clear to letting this go. He is a good guy. Flynn is the subject in the russia investigation and today the president tweeted again that the probe was a witchhunt. He also defended one of his former advisers, carter page, writing democrats have excoriated him. In an interview today, page denied any wrongdoing. I think its going to be such an open and shut case. Reporter well before he oined the trump campaign, page was named as male1 in a fbi case that led to the 2015 arrest of russian spies in new york. Court papers allege the russians tried to recruit page. There are now questions about whether he was properly vetted by the trump campaign. People knew me very well, going back many years, so, not directly within the campaign, but people i knew. Reporter Democrat Eric swalwell is on the house intelligence committee. Carter page is certainly an individual who we would like to hear from, as we would like to hear from any individuals who had contact with the russians during the time of the interference campaign. Pentagon officials and military contractors are still smiling over the successful test of a new antimissile system and theyre planning another test for next year. The military launched a missile carrying a dummy warhead from an island in the pacific. It then launched an intercepter missile from a base in california. And the dummy warhead was destroyed. The test comes amid north koreas increasing threats. David martin has more. Reporter since north korea has said it is finishing work on an intercontinental ballistic missile, this was important that the United States has the capability at least under test conditions to shoot down an incoming icbm. Lifting off from a tiny island in the middle of the pacific ocean, the missile was designed to fly at the trajectory and speed that north korea may be able to launch three years from now. Vice admiral james searing spoke to reporters from his Operations Center in colorado. This is exactly the scenario we would expect to occur during an actual operational engagement. Reporter the plume of the missile was detected by a satellite, which triggered the launch of an interceptor missile from california. The interceptor carried a 5footlong kill vehicle which maneuvered into the path of the incoming warhead. This is what it looked like to infrared cameras. We have information it was a complete obliteration, a direct hit. Reporter this giant seabased radar helped track it as it raced toward space at four miles per second. If a real missile were fired with little or no warning, the radar might not have time to get into position. Its hard to think of the United States in an arms race with an impoverished country like north korea, but that is essentially whats happening. U. S. Missile defenses racing to keep ahead of north Korea Nuclear missiles. If north korea ever does attack the United States, the missile will be tracked by radar in the arctic. The u. S. Maintains an air base in green land. Jeff glor paid a visit. Reporter the air base 750 miles inside the Arctic Circle is not easy to reach or maintain. But the u. S. Did just complete a significant upgrade for space and Missile Defense there. One of several Early Warning systems being improved worldwide. With developments in north korea and russia coming daily, its not just on top of the world but on top of many military minds. On one of the most isolated pieces of land on earth, a base with no roads leading in, a island covered more than 80 in ice. The air force needs to stay constantly connected to the sky. 900 miles from the north pole and five hours flying time away from russias Industrial Hub is the american airfield. Reporter at the height of the cold war, the air base was a vital part of u. S. Strategy and symbolism. Today we were invited on base by colonel Christopher Eagan who took charge of thule just last year. We have a unique access this far north that the department of defense does not have anywhere else. Reporter in training sessions, air men learn to surveil the sky, always on alert for the worstcase scenario, a missile fired froms yeah. Heat signals from launches are typically first picked up by satellites in space. But radar on the ground remains essential to track after that. And no u. S. Base sits farther north than thule. It is the Halfway Point between washington and moscow. The location of the 12th space warning squadron. Their 20 billion radar just got a 40 Million Software upgrade. One of six Early Warning systems like this around the world being improved. More than 3500 antennas here can see 3,000 miles into space. Why is this so significant . Because as the technology changes, it becomes more accurate and with the proliferation were seeing across the globe theres more interest in being able to take measures against them. With the evolution of time weve gone away from aircraft to radar. The mission may have changed. But the access to location remains the same. Reporter thule is now home to only 200 military personnel. They come for a year at a time, climate and conditions are considered too harsh beyond that. I got here last june. Reporter michael ferrar is the base chaplain. Its an a mazing mission, who else can say you went to the top of the world. Reporter that said, its an adjustment. Oh, yeah. You dont hear birds. Theres no trees. Reporter never mind not seeing daylight for four months. I tell you what, when people said not seeing the sun for 100 days was hard, as a chaplain, i was thinking, we can get through anything, but it was hard. Reporter those willing to make this trip often cite the brutal beauty of greenland. Theyre also keenly aware of the mission. When you see how much attention folks are paying to the Arctic Circle now, especially from a military perspective, it has to put you on edge. The increased interest on the political side of the house is interesting. But weve invested for the last 60 years in the capabilities here. When our most important resources are people and theyre that trained and they want to be here, the rest goes away. Reporter the sun wont set again in thule until august. It wont rise from november to february. It may seem hard to believe, but the vast majority there volunteer, sometimes for multiple tours. But for only 7 a month, saster. Ridx helps break down waste.
