Feeding tube treatment for Sharon

Doctors said the latest procedure was successful

Doctors have inserted a feeding tube into the stomach of Israeli PM Ariel Sharon, who has been in a coma since surgery for his stroke on 4 January.

Doctors said the latest procedure - carried out under general anaesthetic - was successful.

Israeli TV has reported "positive signs" in that Mr Sharon, 77, responded to commands to move his eyes and a hand. He remains critical but stable.

Interim Prime Minister Ehud Olmert has assumed Mr Sharon's powers.
