A key witness today in a special court identified two AK-47 rifles allegedly used by Pakistani gunman Mohammed Ajmal Amir Kasab and his accomplice Abu Ismael to kill people in Mumbai on November 26.

When the weapons were being identified, accused Kasab was laughing at the witness and shaking his head indicating that the weapons did not belong to him.

This invited the wrath of Judge M L Tahaliyani who warned Kasab to behave properly in the court. The judge told him that all the time he was seen laughing. "Keep away this casual attitude and show some seriousness," the judge said.

The witness, police sub-inspector Bhaskar Kadam, who had participated in an encounter with the two suspected terrorists, said, "These two weapons were used by Kasab and Ismael (Kasab was held, while Ismael was killed)."

He told the judge that one Ak-47 rifle was carried by Kasab while the other one by Ismael. The rifle with Ismael belonged to Additional Commissioner of Police Ashok Kamathe, who was killed by the duo in another gunfight on the same day near Cama hospital.

Kadam also informed that along with the AK-47 rifles, two pistols of 9mm were also seized from the accused. One of them was a Pakistani make and name of the company mentioned was "Diamond Nadi Frontier Arms Company, Peshawar".

This indicates that weapons had been brought from Pakistan, Special Public Prosecutor Ujjwal Nikam said.
