And new evidence shows disturbing evidence of just how big the Terror Network is across europe. We have correspondents in france and belgium. First up, allen pizzey who is in brussels with the latest. Good morning. Reporter good morning. As the effort to break the terror cell that kered out the brussels bonks goes on, belgian officials are coming under increased scrutiny and criticism what is seen as a series of intelligence failures. In an operation that played out in full view, Belgian Police shot a man who was spoed witted a suspicious bag at a park bench. Police approaching and then a young girl stepping out of the shelter and led to safety and then armed police move in. Targeted raids in an area where earlier in the week, police found a bomb making factory they said was connected to the Brussels Airport and subway attacks. The raid is uncovered as alarming evidence of a europewide jihadist cell of those connected in belgian and in paris in november. Two brothers who died as suicide bombers in the attacks here last week were known to police as petty criminals and potential terrorists. Ibrahim bakraoui who blew himself up in the airport had been arrested and escaped from turkey. His brother khalid who died in the subway attack was subject to an International Arrest warrant after the paris attacks. Officials told cbs news the brothers were on the radar of law enforcement.

The authorities announced that Brussels Airport wont open before tuesday at the earliest. Allen pizzey, thanks. Now to the paris connection. Counterterrorism officials there say an arrest broke up a plan for yet another attack but that is not clearing them of some harsh criticism. Debora patta is in the french capital with more on that. Reporter good morning. The arrest struck a series of blows across european borders but there was criticism over why the police took so long to make rare instance of french and belgian intelligence authorities working together. His capture in paris had a domino effect resulting in more arrests across the border in belgium. Kriket is a 35yearold French National who lived in molenbeek. He was convicted in a Belgian Court of recruiting isis members and funding through fraud and theft. He was sentenced to ten years in jail but by then he had left for syria. The same trial also found guilty, one of the leaders of the november paris attacks abdelhamid abaaoud. French president was quick to take credit for cracking open this Jihadist Network but had to s concede they did not know what they were dealing with. We had success in finding the terrorists he said yesterday at the president ial palace, even though the one that the attack in paris and brussels is in the process of being annihilated, they are still a threat weighing on us. This woman represents the families of the paris attack victims. Over the french government failure to prevent the blood bath. She says krikets arrest is not something to boast about. Because of what we see in policing and their services, abdeslam and abaaoud were captured. Not just because of the good job of police and intelligence service, but also because there was people giving information because they dont want to be any more a target by terrorist people. Reporter she is outraged that it took so long, given that kriket was wellknown to the intelligence agenci and not been left crossing border freely, and this is reporter she told us that many of these jihadists remain under the radar because of their connections to the criminal be under world. She believes that counterterrorism units and Crime Fighting agencies are going to have to join forces to prevent further attacks. Debora patta in paris this morning, thank you. We are learning more about a Young American who survived the attack in belgian. Mason wells was at the airport at the time and survived the attack. He told cbs news he was just 30 feet from the first explosion. The blast was very loud. And i think it actually picked my body off the ground for a quick second and the whole ride of my body got really hot and really cold. When the blast went off, i actually saw fire in front of my face, on the ground. The four of us were actually kind of surrounded by fire for quick moment. Such a frightening image. Masons parents flew from sandy, utah, to join their son in belgium on friday. The reunion with him was undescribable. We are so proud of mason. Hes got a lot of faith and hes very positive. He keeps reassuring us that hes going to be okay. Mason jokes that he may have been born under a lucky star. He was in paris at the time of the november terror attacks and he was just a block away from the bombing at the Boston Marathon three he years ago. In iraq, the kej toll from the suicide bombing at a crowded soccer stadium 30 miles from baghdad has climbed to 41. The game had just ended and a trophy was being presented to the winning team when the bomber detonated the explosives. Isis is claiming responsibility for the attack. 105 people were and its Coalition Partners are gaining ground in the fight ens isis. U. S. Forces killed a top isis operative this week who played a role in terror plots outside of syria and iraq. Julianna goldman is in our Washington Bureau with the latest. Reporter good morning. American commandos originally planned to capture imam to gather intelligence on isis but at the last minute decided to open fire on his vehicle instead which is believe to have killed the man who served as the finance minister for the terrorist group. The removal of this isil leader will hamper the organizations ability to conduct operations both inside and outside of iraq.

Now we have taken out the leader who oversees all of the funding for the organization and hurting them to pay fighters. Reporter this month a u. S. Air strike killed a man known as omar, the chechen, who was considered to be the isis minister for war. We are systematically eliminating isil arbitration cabinet. Reporter carter and Joseph Dunford said momentum against isis in iraq and syria is on their side but striking leadership is necessary leaders can be replaced. I think a lot of reasons for us to be optimistic about the next the next several months. By no means would i say we are about to break the back of isil or the fight is over. Reporter dunford said more u. S. Troops will be needed. We will discuss with the president in the coming weeks to further enable our support for the forces. Reporter they have asked for several more trainers of soldiers to build up the forces and gunships to fly mission in support of iraqiro attempting to retake the key city of mosul. Secretary and i both believe that there will be an increase to the u. S. Forces in iraq in the coming weeks. But that decision hasnt been made. Reporter u. S. Officials, including dunford and secretary of state john kerry, are saying that isis losses on the ground in iraq are fueling the push for attacks elsewhere like what we saw the past week in brussels which for the terrorist Group Highlights a show of strength and vast network its been able to build abroad.
