A lawyer for Pakistan's most powerful intelligence agency has told the country's top court that it held seven suspected militants who were sought by the judges for more than a year and a half without sufficient evidence to try them.

The lawyer for the Inter-Services Intelligence agency, Raja Irshad, told the Supreme Court on Monday that officials held the men because they were convinced they were dangerous.

The seven men were among 11 suspected militants captured in 2007 and 2008. An anti-terrorism court ordered them freed in 2010, but they were picked up again by the ISI.

Four died in custody under mysterious circumstances.

The ISI produced the seven surviving, but ailing, men in court last February in response to a judicial order.
