CALCUTTA, India, Nov. 28— Foreign Minister Jagjivan Ram said today that Indian troops had been given permission to move as deep into Pakistan as the range of the Pakistani guns shelling them.

It was not clear whether this was a real distance limit or just a publicly stated policy designed to disguise a much deeper Indian involvement in Pakistan. But under Mr. Ram's rule Indian forces could attack some key Pakistani strongholds.

[The Pakistan radio said India had launched a new offensive against East Pakistan, using two divisions, three armored regiments, artillery units and air sup port, according to a Reuters dispatch. The broadcast said the attacks took place in the widely separated Sylhet, Dinajpur and Jessore districts.]

He Outlines Sequence

Mr. Ram, speaking at a Calcutta political rally that rang with cries for Pakistan's defeat, also said that the Indian‐sup ported Bengali insurgents “are advancing against Pakistani troops in such a way that I have no doubt that the freedom of Bangla Desh [Bengal Nation] is now probably only a matter of days.”

The Defense Minister, who spoke for nearly an hour in Hindi, told the crowd of about 50,000:

“When the Pakistanis started creating trouble on the borders, I told my generals to take action. When it became worse, I told them to cross the borders to silence the guns. Now they've been told that if it becomes necessary, they can advance as many miles into Pakistani territory as the range of the Pakistani guns.”

Most of those guns are medium artillery pieces, such as 105‐mm. howitzers, which have a range of up to nine miles. But the Pakistanis are believed to have some long‐range pieces as well, such as 175‐mm. guns, which can fire shells more than 15 miles.

Confusion About Crossings

Many important military objectives in East Pakistan fall within these limits. Comilla is only five miles from the Indian border and the army cantonment outside the city is only 15 miles away. Jessore and its cantonment are 15 miles from the border, Sylhet 19 miles, and Dinajpur about 9 miles.

If the Pakistanis fired on the Indian border from these positions, according to the policy stated by Mr. Ram today, Indian troops could move on them.

The Indian Government continues to insist that its troops are crossing the border only, “in self‐defense.” But there has been some confusion about this.

At a briefing for newsmen yesterday at Boyra, near the scene of an Indian border cross sing and tank battle, Col. Clarence L. Proudfoot of army intelligence said: “I want to say, I want to stress, that our troops went in because the Mukti Bahini (Liberation Forces) called for help. They said they were in mortal danger, because Pakistanis were moving ahead through their territory.”

Indian officials have not been clear about the distance of the intrusions. A spokesman in New Delhi last week said of the Boyra intrusion: “I can't say the length, it is only a short distance.” Colonel Proudfoot said it was three miles. Independent sources said it was much deeper.

The Indians have announced only three border crossings, but authoritative sources have re ported many more, and there is evidence that some Indian troops have remained inside East Pakistan, although the Indians deny this.

Of the three acknowledged intrusions, one was at Boyra, about 60 miles northeast of Calcutta, and two at Balurghat, 125 miles further north.

The latest one, at Balurghat, was announced by the Government today in a statement distributed to the press. It said:

“Indian troops were compelled to take fresh defensive action in the Balurghat‐Hilli area yesterday following renewed Pakistani shelling. Ac cording to the latest reports, the fighting is still going on. So far, three Pakistani tanks have been destroyed in this encounter. Further details are awaited.”

At the Calcutta rally this afternoon, organized by the governing New Congress party and held at Deshbandhu Park, the mood on the speakers plat form was hawkish,

“We will make shoes out of Yahya's skin,” said one speaker, in a reference to the Pakistani President, Agha Mohammad Yahya Khan.

“India will break Pakistan to pieces,” said another.

“Yahya says he may go to war in 10 days,” said a third. “Well, we're ready to crush him in 10 minutes.”

The applause was infrequent and muted.

Defense Minister Ram, though somewhat less flamboyant than the local politicians who spoke, was nevertheless blunt.

“Even today, I don't want a war,” he said, “but it the Pakistanis create trouble, we'll fight a war on Pakistani soil, not on India's. I don't want to destroy Pakistan, but I want to teach them a lesson.” He went on:

“All three armed forces—the army, navy and air force—are impatient to do something. I have come to assure you, on behalf of our soldiers on the borders, that you have nothing to fear.”
