MANCHESTER, UNITED KINGDOM — British officials are probing how the suicide bomber behind Monday night’s attack in Manchester was able to prepare for and execute the atrocity. <br /> <br />The attack — which killed 22 people and injured 59 — took place during a concert by American singer Ariana Grande at Manchester Arena on Monday evening. According to the Telegraph, the suicide bomber, identified as 22 year-old Salman Abedi, detonated what appeared to be a nail bomb in the arena’s foyer. <br /> <br />British security services are investigating how Abedi came into possession of the bomb. <br /> <br />According to the BBC, one possibility is that Abedi was taught how to make the explosive by someone linked to ISIS or al-Qaeda. He reportedly traveled to Libya as recently as three weeks ago, and may have learned there. <br /> <br />Another scenario is that he was self-taught and may have built the explosive himself. However this would have required knowledge of engineering. <br /> <br />Abedi may have also been given the device, which suggests a skilled bombmaker may be resident in the UK. <br /> <br />British Prime Minister Theresa May this week raised the threat level country’s terrorism threat level to “critical,” meaning another attack could occur at any time. <br /> <br />The last terrorist bombing in UK happened in 2005, with recent attacks involving the use of knives or vehicles.
