Four men charged in connection with an anti-terror operation targeting an alleged network of terrorist recruiters are due to appear in court.
All were held during a series of raids across London overnight on September 1, including at a Chinese restaurant in the Borough area of the city.
The operation has also involved anti-terror officers searching an Islamic school in East Sussex.
Musa Akmet, 47, Mustafa Abdullah, 24, and brothers Hassan Mutegombwa, 20, and Yassin Mutegombwa, 22, were all charged under anti-terrorism legislation in connection with the operation. All four men will appear before City of Westminster Magistrates in London.
Akmet, of Eltham, south east London, was charged with one count of possessing information likely to be useful to a terrorist contrary to Section 58 of the Terrorism Act 2000. He was also charged with possessing a firearm - a 16mm mini flare launcher - without a firearms certificate.
Abdullah, of Stockwell, south London, was charged with one count of possessing information likely to be useful to a terrorist.
Scotland Yard said Hassan Mutegombwa had been charged with one count of procuring funds for terrorism contrary to section 15 of the Terrorism Act 2000. Yassin Mutegombwa was charged with three counts of receiving training for terrorism, a new offence contrary to section 6 of the Terrorism Act 2006. A total of eight men remain in custody in connection with the investigation.
The terrorism-related charges against Musa Akmet and Mustafa Abdullah allege that, on September 1 this year, they "without reasonable excuse possessed a record containing information of a kind likely to be useful to a person committing an act of terrorism".
The charge against Hassan Mutegombwa alleges that, on July 23 this year, he "invited another to provide money and intended that it should be used, or had reasonable cause to suspect that it may be used, for the purpose of terrorism".
The first two charges against Yassin Mutegombwa allege he received terrorism training at a woodland area near Matley Wood Caravan and Camping site, Beaulieu Road, Lyndhurst, Hampshire. The third charge alleges he received terrorism training near Pondwood Farm, White Waltham, Berkshire on June 18 this year.
