Iran's state-run Arabic satellite television Al-Alam yesterday aired new footage of two detained British naval servicemen.

The two British naval personnel were shown separately in two video clips, both pointing to a big map of the northern Gulf waters. They were talking in front of the camera, but their voices could not be heard.

Al-Alam TV said they "have confessed" to entering Iranian waters "illegally" while on an inspection mission, adding the captured sailors had said that they were treated well.

The two are among the 15 British naval personnel who were seized on March 23 by Iranian forces when they were patrolling off the Iraqi borders.

Iran has insisted that the British boats illegally entered its territorial waters. But Britain said its soldiers were in Iraqi territorial waters.

On Friday, Al-Alam showed a footage of a male British naval serviceman, Nathan Thomas Summers, who confessed to entering Iranian waters "without permission."

On Wednesday, the same Iranian state-run television broadcasted for the first time a video footage of the recently detained British sailors, including Faye Turney, the only female among the 15 captive British naval personnel.

Turney was shown on the television admitting "illegal entry" into Iranian waters.
