ISLAMABAD, Pakistan, Nov. 24—Pakistan announced today that she was calling up her military reserves and said that heavy fighting with Indian forces was continuing in the eastern region.

A military spokesman said Pakistani forces were driving back Indian advances made two days ago into East Pakistani territory. He said Pakistan had recaptured a border outpost at Chanderpur that had fallen to the Indians in the Sylhet District of northeastern East Pakistan.

But lie said that two East Pakistani villages, Chuagacha, in Jessore District in the westem part of the province, and Atgram, in Sylhet District, I were still in Indian hands. A new Indian thrust was said to have been made into Dinajpur District in the north, but according to the spokesman the attack was repulsed with heavy enemy losses.

Shipping Restricted

In Karachi, the naval authorities warned all shipping to remain at least 75 miles from the West Pakistani port during the hours of darkness. Pakistan has charged that Indian ships have attacked freighters supplying East Pakistan, sinking one grain ship.

In. Dacca, about half the United Nations relief workers in East Pakistan took part out of the area after guerrilla attacks on United Nations vehicles. Two boats carrying the organization's banner were attacked and sunk yesterday. [Details on Page 15.]

[The Pakistani radio said the Government's forces had blunted two attacks, including one supported by planes, and had killed 100 Indians and damaged two tanks, The Associated Press reported. Pakistani losses in the fighting were put at seven killed and 11 wounded. Earlier the radio said Pakistani troops had killed more than 200 Indian soldiers at Sylhet.]

Islamabad Seems Calm

Meanwhile, in the wake of the proclamation of a national emergency and accompanying the call‐up, which applies to all reservists and all former navy personnel under age 50, the people of West Pakistan were advised in broadcasts and newspapers to dig trenches.

The embassies of the United States, Britain, France and West Germany, among others, advised their citizens living in border areas to move to safer places. The dependents of most diplomats and other foreign residents of East Pakistan were evacuated from that strife‐torn province last March, when the army crackdown against the Bengali independence movement began, and they have not returned.

There were hew physical signs of war here in Pakistan's capital or in the nearby city of Rawalpindi. A dozen or so workers were digging slit’ trenches near Government building in Islamabad, but otherwise life appeared unchanged.

Accredited diplomats seemed, for the most part, uncertain as to the seriousness of the situation.

Pakistan maintains that in the last three days some 100,000 Indian troops, supported by 100 tanks, air power and artillery, have attacked East Pakistan, seizing some territory. India contends that her forces remain under orders not to cross the frontier and that most of the fighting has involved Bengali guerrillas, not regular Indian troops.

So far no incidents have been reported along West Pakistan's long border with India.

At this point no foreign observers either in India or in Pakistan are known to be present in the area where the fighting has taken place. Consequently, foreign embassies apparently have been deprived of independent intelligence on the situation.

Foreign military observers believe that if India had mounted an all‐out offensive against East Pakistan, her forces probably would have penetrated much deeper than they apparently have.

Change in the Atmosphere

On the other hand, there has been a perceptible change in the diplomatic atmosphere in the last 48 hours, and fears are much more general that allout war may be imminent.

Diplomats of a number of countries, including the United; States, have met with the Pres; ident, Gen. Agha Mohammad Yahya Khan, in the last few; days. All have urged caution; and restraint and all have been told that Pakistan welcomes; any diplomatic restraint that can be brought to bear against alleged Indian aggression.

A 12‐member delegation from China arrived today, partly to; inaugurate a large industrial complex built with Chinese aid, and also to discuss Pakistan's needs during the current emergency.

Enormous red and gold Chinese flags have blossomed in; Rawalpindi, as have posters saying ‘'Oust Russians.” China supplies Pakistan’ with arms while the Soviet Union is arming India and recently concluded a treaty with her.
