 Belgian prosecutors say a man arrested on Friday has admitted being the "man in the hat" seen with the bombers who attacked a Brussels airport. 
 
 They say Mohamed Abrini told investigators he was at the scene of the 22 March suicide bombings. 
 
 Abrini is also wanted in connection with the attacks in Paris that killed 130 people in November. 
 
 He is one of six men arrested in Brussels on Friday. Four have been charged with terror offences. 
 
 The attacks at Zaventem airport and a metro station in Brussels left 32 people dead. 
 
 Officials believe those who carried out the Brussels and Paris attacks were part of the same network backed by so-called Islamic State. 
 
 Abrini, a 31-year-old Belgian of Moroccan origin, confessed to being the "man in the hat" after being confronted with the evidence, the federal prosecutor said. 
 
 "He said that he threw away his jacket in a rubbish bin and sold his hat after the attack," the statement added. 
 
 There is no word from the suspect himself or his lawyer. 
 
 Abrini's fingerprints and DNA were found in two "safe houses" in Brussels, as well as in a car used during the Paris attacks, investigators said earlier. 
 
 The BBC's Damian Grammaticas, in Brussels, says the apparent confirmation that Abrini is the man seen in the airport footage is a "huge" development for Belgian authorities, whose response to terrorism has come in for criticism.

 The other suspects charged on Saturday were named as Osama K, Herve BN, and Bilal EM. 
 
 They are all accused of "participating in terrorist acts'' linked to the Brussels bombings. Two other people arrested on Friday have been released. 
 
 Osama K, identified in media reports as Swedish national Osama Krayem, was the man seen with the suicide bomber at Maelbeek metro station just before the attack on 22 March, investigators say. 
 
 They also say that he bought bags used by the two bombers who struck at Zaventem airport on the same day.

 Osama K is believed to have entered Greece from Syria with migrants last year, using a fake Syrian passport. Prosecutors believe he was driven from Germany to Belgium by Paris attacks suspect Salah Abdeslam in October. 
 
 Herve BM, described as a Rwandan national, and Bilal EM are both suspected of having offered assistance to Abrini and Osama K. 
 
 Abrini is thought to have been filmed at a petrol station with Abdeslam two days before the attacks in Paris in November. 
 
 Abdeslam, a Belgian-born French national of Moroccan descent, was detained in Brussels in March, days before the attacks in the Belgian capital. 
 
 The latest charges follow days of arrests and raids in Brussels. 
 
 On Saturday, heavily armed police carried out a search in the Etterbeek area of Brussels. The target was a flat which police believe may have been used as a safe house by the militants. ||||| The 31-year-old, also thought to have been involved in Paris attacks, made confession following arrest on Friday 
 
 Mohamed Abrini admits to being 'man in the hat' at Brussels airport 
 
 After nearly three weeks of frantic searching, Belgian authorities have announced they have finally arrested and identified the elusive “man in the hat” spotted alongside two suicide bombers who blew themselves up at Brussels airport on 22 March. 
 
 In a statement on Saturday evening, Belgian prosecutors said Mohamed Abrini, 31, the last identified suspect at large from the Paris attacks on 13 November, had confessed to being the vest- and hat-wearing man whose video image had been widely circulated by authorities. 
 
 “After being confronted with the results of the different expert examinations, he confessed his presence at the crime scene,” the statement said. 
 
 Paris and Brussels: the links between the attackers Read more 
 
 The revelation that a Paris suspect escorted two of the Brussels bombers to their deaths at the city’s Zaventem airport is among the strongest signs yet that the attackers who struck both cities killing a total of 162 people were intimately linked. 
 
 Abrini, who was arrested on Friday in a Brussels police raid, was one of four suspects charged on Saturday with “participating in terrorist acts” linked to the deadly Brussels suicide bombings that resulted in 32 deaths and 270 injuries at the airport and at the city’s Maelbeek subway station. 
 
 The prosecutors’ office said Abrini threw away his vest in a rubbish bin and sold his hat after the bombings. 
 
 Authorities had been frantically seeking the “man in the hat” since he was filmed alongside the two bombers just before the airport attack. Belgian authorities recently released more footage of the man leaving the airport in the wake of the bombings, walking down streets and past a hotel.

 The other three men charged were Herve BM, a Rwandan national; Bilal EM, 27; and Osama K, reported to be a Swede whose full name is Osama Krayem. Prosecutors said they identified Osama K as the man present at the time of the metro attack. 
 
 All four men were charged with participating in “terrorist murders” and the “activities of a terrorist group”. Two other suspects arrested on Friday have been released. 
 
 
 
 Abrini had been on Europe’s most wanted list since being identified as one of two suspects seen on CCTV travelling by car to Paris two days before the attacks on the French capital in November. 
 
 
 
 However, he disappeared before 130 people were killed in coordinated assaults at the national stadium, bars, restaurants and the Bataclan concert hall. 
 
 Abrini, who has Belgian and Moroccan nationality, grew up in Brussels and has a history of petty crime. His younger brother died in Syria in 2014 after joining Islamic State. Abrini is believed to have travelled to Syria last summer. 
 

– Mohamed Abrini, who was arrested Friday in Brussels, reportedly confessed Saturday to being the "man in the hat" long sought by authorities in connection with the attacks that killed 32 people in March, ABC News reports. According to the BBC, a federal prosecutor says the 31-year-old Belgian admitted to being present during the bombing at the Brussels airport after being confronted with the evidence against him. He was charged Saturday with terrorist murders and participating in the activities of a terrorist group. Abrini has been on Europe's most wanted list since the November attacks in Paris that killed 130 people, the Guardian reports. Authorities believe he played a part in those attacks as well; his fingerprints were allegedly found in a car used in the Paris attacks. Authorities say Abrini threw his vest in a garbage can and sold his hat following the Brussels airport suicide bombing in which his two accomplices were killed. He is believed to have travelled to Syria last summer, and his younger brother died in that country in 2014 after joining ISIS. Six people total were arrested Friday in Brussels. Two of them were released, and the remaining four—including Abrini and another man suspected of being present at the Brussels subway bombing—were charged with terrorism-related crimes Saturday.
