The US and UK are in talks about the fate of two men from London who were detained in Syria last month on suspicion of terrorist activity, Home Secretary Amber Rudd said.
Late Monday, Rudd said the captured men, Allexanda Kotey and El Shafee Elsheikh, should go on trial, reports the BBC.
They are suspected of being members of an Islamic State (IS) cell that killed Western hostages.
The men have been stripped of their UK citizenship.
It has been suggested they could be sent to the US military prison at Guantanamo Bay.
Alternatively, they could be put on criminal trial in the US or at the International Criminal Court, The Hague, which can prosecute people for genocide, war crimes, crimes against humanity and aggression, the BBC reported.
Rudd said: "We're absolutely committed to making sure that they are tried.

"These people should face the full force of the law. I can't be drawn at the moment into where that will take place. But I am certain, because we'll be working with the Americans to ensure this, that they will face justice."
The men are accused of being the last two of four UK IS members known as "the Beatles", so called because of their British accents.
