Four men were charged on Thursday with offences over an alleged plot to commit an act of terror in the UK, said London police.
The police arrested the men from east London last week before an attack in Manchester which killed 22 and wounded dozens.

Muhammad Abid, 27, was charged with having information which might have assisted police in apprehending and prosecuting Haque, and Abuthaher Mamun, 18, was charged with intending to assist another person to commit acts of terrorism.
A fourth man Nadeem Ilyas Patel, 25, was charged with conspiring with Haque to possess a firearm or imitation firearm "with intent to cause fear of violence."
They are due to appear at London's Westminster Magistrates' Court on Friday.
