Terrorism: The FBI and MI5 chiefs say that it is harder to stop terrorist attacks when there are only a few people involved.

According to the FBI's head, it is becoming harder to find intelligence to stop terrorist attacks. This was stated at a London meeting.

Christopher Wray stated that the US security agencies and MI5 are witnessing more attacks using crude weapons and very little training.

Wray stated that it was crucial for security services to quickly share intelligence after the joint meetings with MI5.

Ken McCallum, head of MI5, said that they were facing a "very difficult mix of risks".

According to the FBI director, there are "very few dots" in intelligence about planned attacks. He also stated that it was harder to connect them.

He explained that it was crucial to work with MI5 in certain cases.

He said, "If we aren't super lashed up, we're going be missing the only picture out there - it's got to occur really fast."

He stated that technology and travel had "blurred" the lines between domestic and foreign threats and that encryption provided by technology companies was allowing terrorists and criminals to operate in an "unfettered" space.

McCallum stated that approximately one fifth of all terrorism investigations in Great Britain were related to neo Nazi, racist ideology, or another related extremism. This rate has remained relatively steady.

He stated that MI5 continues to see a growing role in the recruitment of juveniles and a keen interest in weaponry.

Both men stated that their agencies could cover a wider range of threats because they worked together.

The FBI director stated that he met British intelligence and security officers during this week's visit, which was in celebration of 80 years of formal cooperation between the FBI (USA) and the UK.

Friday afternoon, he visited China and looked at case studies about intelligence operatives from both Russia and China.

McCallum stated that the Russian diplomats expelled after the Salisbury poisonings of 2018 and continued refusal to issue visas had prevented Moscow from rebuilding its presence, and had limited the threat to the UK.

Mr Wray stated that cyber threats were also high on the agenda of discussions.

The two security chiefs made a rare joint public appearance Wednesday to warn that China is posing an "immense threat".

They spoke with academic and business leaders at the MI5 headquarters in Thames House, central London.
