Kansas lawmakers are discouraging any talk of moving detainees from Guantanamo Bay to Fort Leavenworth, Kansas.

Senators Sam Brownback and Pat Roberts told their colleagues that the disciplinary barracks at Fort Leavenworth lack the space and security to handle the detainees.

Fort Leavenworth is a military base, but the senators said it doesn't have security equal to the "supermax'' penitentiary in Colorado.

The Disciplinary Barracks also is surrounded by the city of Leavenworth, and the senators claimed that makes it impossible to keep detainees at a sufficient distance from the general public.

Speculation that government officials plan to close the Guantanamo Bay detention center has grown since the Supreme Court ruled this month that detainees there could challenge their detention in federal court.

A Senate bill introduced last year would require the closure of Guantanamo and designate Fort Leavenworth as the new jail. That bill has been stuck in committee.

The Guantanamo jail holds about 270 men suspected of terrorism or of having links to al-Qaida or the Taliban.
