CAIRO (AP) — A senior security chief has testified at the trial of Hosni Mubarak that his superiors told troops to drive armored vehicles into peaceful protests but he never heard orders to fire live ammunition.

The former Egyptian leader and his security chiefs are facing charges of ordering the use of lethal force against the protests that eventually ousted Mubarak.

Maj. Gen. Hassan Abdel-Hameed, who was first deputy interior minister for training, tells The Associated Press that he was ridiculed when he objected to plans to drive armored vehicles into protesters and fire large amounts of tear gas at them.

Abdel-Hameed told the AP on Thursday that some policemen used live ammunition to break up the rallies. Abdel-Hameed has not been charged in the case.
