Four men from south London have been charged following a series of police raids which targeted an alleged network of terrorist recruiters.
Raids also took place at a Chinese restaurant
One of them, Yassin Mutegombwa, 22, is accused of receiving training in the use of weapons in woodland in Hampshire and at a location in Berkshire.
Three other men were charged with other terrorism offences.
All were held during a series of night raids in London on 1 September, including at a Chinese restaurant.
Mr Mutegombwa, of Upper Norwood, is charged with three counts of receiving terrorism training.
His brother Hassan Mutegombwa, 20, also of Upper Norwood, is charged with one count of procuring funds for terrorism.
Musa Akmet, 47, of Eltham, is charged with having information useful to a person committing an act of terrorism, as well as possession of a firearm, under the Firearms Act.
And Mustafa Abdullah, 24, of Stockwell, is charged with having information useful to a person committing an act of terrorism.
The raids in London led to 14 arrests, including 12 at the restaurant in Borough, although two people have been released.
Anti-terrorism officers also swooped on the Jameah Islamiyah Secondary School in Mark Cross, near Crowborough, East Sussex, which they continue to search.
Sussex Police said investigations at the school could take weeks but that no arrests had been made there.
The school was set up in 2003 as an Islamic teaching facility for boys aged between 11 and 16, according to Ofsted inspectors.
BBC home affairs correspondent Margaret Gilmore says the charging of one of the men has made legal history.
"One of the men has been accused of funding terrorism under a law which has been used before but the second man is accused for the first time under a specific part of the Terrorism Act 2006 with receiving training for the purposes of terrorism."
The men will appear in court on Tuesday.
Among those being held is Abu Abdullah who is a former associate of the radical Islamic cleric Abu Hamza.
Police said the arrests were not connected to the alleged plot to blow up transatlantic airliners or the Tube and bus attacks in London on 7 July last year.
