Two London men charged with inciting other people to commit an act of terrorism "wholly or partly outside the UK" have been remanded in custody.
The two men are being held in custody in London, police said.
Faiz Baluch, 25, of Wembley, and Hyrbyair Marri, 39, of Ealing, were charged under the Terrorism Act 2000.
The pair, due to appear at the Old Bailey on 21 December, said they were peaceful activists for the independence of Pakistan's Balochistan province.
Campaigner Peter Tatchell was among supporters in the public gallery.
They will appear at the Old Bailey on 21 December for a preliminary hearing.
Both are alleged members of the Balochistan Liberation Army, which was banned by the then home secretary John Reid in 2006.
The men were arrested by officers of the Metropolitan Police Counter Terrorism Command at addresses in north-west and west London on 4 December, and remanded following a hearing at Westminster Magistrates' Court.
Mark Topping, prosecuting, alleged that that Mr Baluch - an Iranian student who lives in Wembley, north west London - searched for torpedoes, explosives and remote controls with which to detonate them on his computer.
Mr Baluch claimed asylum in the UK in 2002.
The prosecution added that "incriminating evidence" was found on a computer belonging to Mr Marri, a journalist from Pakistan, and that £4,000 in cash and CS gas canisters were discovered at his home.
He is charged with having "a weapon designed or adapted for the discharge of any noxious liquid, gas or other thing", police said.
The court was told that father of four Mr Marri was formerly an elected member of Balochistan's regional assembly.
Balochistan borders Afghanistan and Iran in the south west of Pakistan. In 2006, clashes between rebels and government forces in the province killed 145.
