Terrorism: See the heavy police presence outside England vs Lithuania football match (PHOTOS)

Armoured vehicles were deployed to the England vs Lithuania football match at Wembley Stadium tonight, amid fears fans could be targets. 90,000 football fans travelled to Wembley for the World Cup qualifying match, days after attacker Khalid Masood killed four people in an attack on Westminster Bridge and the House of Parliament. Amid a review of security, extra officers and armed patrols were on scene around the stadium to avoid any repeat of Wednesday’s terror in London. There was also a minute’s silence before the kick-off at 5pm. Deputy Assistant Commissioner Neil Basu, the senior national co-ordinator for UK counter-terrorism policing, said: ‘We still believe that Masood acted alone on the day and there is no information or intelligence to suggest there are further attacks planned.

‘Even if he acted alone in the preparation we need to establish with absolute clarity why he did these unspeakable acts to bring reassurance to Londoners, and to provide answers and closure for the families of those killed and the victims and survivors of this atrocity. Tributes paid to the two 'gift of life' teen boys found dead at sea cliffs ‘We must all accept that there is a possibility we will never understand why he did this. That understanding may have died with him.’ He said officers were working to establish whether Masood was ‘a lone actor inspired by terrorist propaganda or if others have encouraged, supported or directed him’. He added: ‘Whilst the attack lasted only 82 seconds it will remain in the memories of many forever.’

Counter-terrorism officers have spent days piecing together what led the 52-year-old to shed his birth name and later unleash carnage on the capital.
