RAWALPINDI, Pakistan, Dec. 12—A Pakistani spokesman said tonight that Indian forces in East Pakistan had warned Pakistani defenders that if they did not surrender, they would be turned over after the war to guerrillas “to be butchered.”

He said that the Indian commander in East Pakistan had released a captured Pakistani officer and had instructed him to take the message to the surrounded Pakistani garrison at Comilla, 53 miles east‐southeast of Dacca.

A spokesman here said tonight that the Comilla garrison would hold out indefinitely and that surrender or acceptance of Indian terms would not be considered. He denounced the reported Indian threat as a contravention of Geneva conventions on warfare.

Military spokesmen continued to describe the situation in East Pakistan as grim, but said that Pakistani troops were beating back Indian forces. More Indian troops have moved into strongholds near Dacca, one spokesman said, but without advancing closer to the provincial capital.

Apparent Lull in West

There were no reports of hostile air activity over West, Pakistan today and the ground war in the west appeared to be at a lull.

Pakistani forces that took the border town of Chhamb in Indian Kashmir last week had not moved across the Munnawar Tawi, a river a few hundred yards away, nor had Indian counterattacks apparently gained any ground.

A spokesman tonight issued the Pakistani estimate of Indian casualties in the fighting to date, but declined to disclose Pakistani casualties.

He said that since Dec. 3, India had suffered 1,096 killed in West Pakistan and 2,214 killed in East Pakistan.

The spokesman said that 122 tanks had been destroyed and 16 captured in West Pakistan and that 23 tanks had been destroyed and 7 captured in East Pakistan.

The air‐raid sirens have been quiet here in Rawalpindi all weekend. It has been almost like peace, as people strolled under a warming sun, only slightly apprehensive about the airplanes above them. The crowing of roosters and the tolling of Sunday church bells contributed to the illusion.

Bombed Almost Daily

In the last week, Rawalpindi had been bombed nearly every clay and its population had come to dread the sirens even when no Indian planes came over. Sometimes, the whistling roar of an enemy jet had preceded the sirens. The people spent their days with their ears cocked for the sounds of approaching danger.

The false peace of the weekend was the result of an air evacuation upon which both India and Pakistan had agreed.

During the past week, various charter flights have taken advantage of truces in the air war to ferry hundreds of foreigners out of Karachi and Rawalpindi. Thousands more have left Pakistan by road, over the Khyber Pass into Afghanistan.

Today, the evacuation traffic was heavier than ever.

Here at Rawalpindi, foreign refugees poured out of the country this morning aboard one Canadian 707, three British jet transports and two Soviet planes.

At Dacca, arrangements were completed and foreigners began leaving. Probably close to 2,000 foreigners left Pakistan by air alone today.

The more than 300 outbound Soviet technicians and diplomatic staff members faced a hostile demonstration of about 2,000 Pakistanis at Rawalpindi Chaklala Airport, which had been bombed or strafed nearly, every morning, sometimes by Soviet‐built planes.

Some youths in the crowd hanged Soviet automobiles with rocks and threw things at the Russians. The Soviet Ambassador, Aleksei A. Rodionov, was struck by a tomato and five cars were reported to have been damaged. Tonight a Pakistani Foreign Office spokesman denied any knowledge of the incident, but a Soviet source said a protest had been lodged.

The Pakistanis, most of them students and women teachers, Jeered the Russians and waved anti‐Soviet signs. A Canadian group, leaving at the same time, hoisted a maple leaf flag to avoid being confused with the Russians.

The Soviet Union, which had provided extensive aid to Pakistan over the years, incurred official wrath here by concluding its mutual‐assistance pact with India and supplying her with arms.

Lest week special flights arranged by Britain, West Germany, Japan, Switzerland, Australia, Canada, the Netherlands and the United States had airlifted refugees from Karachi.

Transport planes from Iran and Belgium were expected later.

Traffic, Too, Is Deadly

At night, air raids or no air raids, traffic accidents continue to take a heavy toll of dead and injured on West Pakistan's roads. Officially, drivers are told to keep their shaded headlights on at night, except during alerts, but most drivers still believe they are required to drive without lights.

Traffic remains heavy. Drivers usually travel at 50 miles an hour under a black sky, without even using parking lights. Pedestrians, bicyclists, ox carts and camels also are on the roads without lights. And there are no street lights.

It has been speculated here that highway casualties may almost equal those of combat in West Pakistan. It is expected that gasoline will be rationed soon and that traffic of all kinds will be reduced sharply.
