Malaysia is to extradite nine foreigners arrested on terror charges last month, officials have said.
Home Minister Hishammuddin Hussein has said the nine have links to international terror organisations and posed "a very serious threat".
Rights activists have said the men are from Jordan, Nigeria, Syria and Yemen.
The suspects are being held under the controversial Internal Security Act (ISA), which allows for indefinite detention without trial.
The nine foreigners were among 50 people arrested as they attended a religious class near the capital, Kuala Lumpur, on 21 January.
Most were released but the foreigners, along with one Malaysian suspect, were kept in detention.
The authorities have not confirmed the identities of the detainees nor which terror group they are suspected of working with.
A rights group condemned the "secretive" detentions and said the government had to show evidence for the arrests.
Syed Ibrahim Syed Noh, chairman of the Abolish ISA Movement, said the government must also ensure the men would be safe if returned home.
The government has faced calls for the ISA to be repealed from groups who say there is too much potential for it be abused.
The act has previously been used to detain opponents of the government and members of the regional militant Islamist group, Jemaah Islamiah.
