(CNN)  -- President Obama has ordered a review of security screening processes after Friday's botched terror attack on a U.S. airliner, White House press secretary Robert Gibbs said Sunday.



Appearing on the ABC program "This Week" and the NBC program "Meet the Press," Gibbs said Obama is receiving regular briefings by his national security staff on the incident in which a suspect allegedly tried to detonate an explosive device on a Northwest Airlines flight from Amsterdam, The Netherlands, making its final approach to Detroit, Michigan.



The suspect, 23-year-old Nigerian Umar Farouk Abdulmutallab, was on a broad watch list of 550,000 names since last month, Gibbs said.



That list does not automatically bring tighter screening of individuals, Gibbs said, and Obama has ordered a review of the procedures for determining which people on the list undergo more stringent checking.



Obama also called for "a review to ... figure out why an individual with the chemical explosive he had on him could get on a plane in Amsterdam and fly into the United States," Gibbs said on NBC.



"The president is very confident that this government is taking the steps that are necessary to take our fight to those who seek to do us harm," Gibbs said on the ABC program.



Authorities on Sunday focused their investigation on how a lone traveler smuggled explosives aboard the Northwest Airlines flight and who might have helped him.



Abdulmutallab, who had a multiple entry visa to the United States, was charged Saturday in a federal criminal complaint.

People on the flight described a chaotic scene that began with a popping sound followed by flames erupting at Abdulmutallab's seat. Jasper Schuringa, a Dutch passenger on the flight from Amsterdam, leaped across the aisle to grab the suspect, who according to authorities suffered burns on his legs.



Schuringa told CNN he saw that Abdulmutallab was holding a burning object between his legs.



"I pulled the object from him and tried to extinguish the fire with my hands and threw it away," Schuringa said. He said he heard fire extinguishers as he pulled Abdulmutallab out of his seat and dragged him to the front of the plane.



In Nigeria, Abdulmutallab checked no baggage on his trip that originated in Lagos on a KLM flight to Amsterdam, where he changed planes to the Northwest flight, according to Harold Demuren, director-general of Nigeria's Civil Aviation Authority.



The suspect had a shoulder bag and went through the normal check-in process with his passport and U.S. visa scanned, Demuren said Sunday. The multiple-entry U.S. visa was issued in London, England, in June 2008 with an expiration date of June 2010, Demuren said.



Abdulmutallab then passed through a walk-through metal detector and put his shoulder bag through an X-ray screening machine, Demuren said. He also said the suspect underwent secondary screening at the boarding gate for the KLM flight, according to officials of the Dutch airline.



The father of the suspect recently contacted the U.S. Embassy in Nigeria with concerns his son was planning something, a senior U.S. administration official said Saturday.



The father -- identified by a family source as Umaru Abdulmutallab -- contacted the embassy "a few weeks ago" saying his son, Umar Farouk Abdulmutallab, had "become radicalized," the senior administration official, who is familiar with the case, told CNN.



A family source told CNN that the elder Abdulmutallab -- who recently retired as chairman of First Bank PLC, one of Nigeria's premier banks -- had contacted the embassy in Nigeria's capital, Abuja, and various other security agencies earlier than the timeline provided by the administration official. The family source said Abdulmutallab went to those agencies about three months ago after receiving a text message from his son.



The source, who lives at the family home in Kaduna in northern Nigeria, said the son informed his family in the text message that he was leaving school in Dubai to move to Yemen. He implied that he was leaving "for the course of Islam."



The family member said Abdulmutallab "had no family consent
