Pakistan's disgraced nuclear scientist AQ Khan has informed a court here that the government has placed a ban on water and medical supplies to him under the garb of a court order.

Khan's counsel Syed Ali Zafar told a bench of the Lahore High Court on Monday that though arguments in a case for easing restrictions on the scientist were going on, the government had barred Khan from going out of his residence even to visit his brother who is critically ill in a hospital.
