The accused insisted, during the hearing, he enjoyed diplomatic immunity and refused to sign the Challan against him.

Raymond Davis, who fatally shot dead two Pakistani citizens in a broad daylight last month, requested the court to grant him diplomatic immunity.

The western media say the detained US national was a CIA contractor in Pakistan.

The court, later, adjourned the hearing till March 3.

Meanwhile, the White House, once again, said the accused national was a diplomat and the issue could not be compromised upon.
