DACCA, Pakistan, Dec. 6 (Reuters)—A Pakistani general said today that Indian troops were now 30 miles inside East Pakistan and that Indian warships were blockading the strategic port of Chittagong.

Maj. Gen. Rao Farman Ali, military adviser to the Governor of East Pakistan, said the main Indian thrust was coming from the northwest salient where Indian troops, supported by Russian‐built tanks, had penetrated 30 miles into Pakistani territory.

The general, recognized as one of the leading military figures in East Pakistan, said that the Indian aircraft carrier Vikrant and four destroyers were effectively blockading Chittagong on the Bay of Bengal.

He said at a news conference that there was no chance of lifting the blockade for some time but that supplies had been stockpiled.

7 Divisions Reported in Action

The general said that seven Indian divisions and 10 or 11 Indian Air Force squadrons had been deployed against Pakistani forces in the Eastern wing.

“We are fighting a defensive battle in the East and by the very nature of the operation are likely to lose territory,”, General Farman said.

“Our aim is to cause attrition on the enemy to the extent that his advance comes to a grinding halt, preferably in a place of our choosing,” he added.

The main effort in the western sector of East Pakistan was around the strategic town of Jessore, he said, while in the eastern sector it was along a wide front stretching from Sylhet down to Akhaura, 45 miles, from Dacca and Comilla.

“Despite the Indian claims, can assure you that Jessore has not fallen and there is no question of it falling without a terrible fight,”, he said.

He added that steps had been taken against the possibility of a parachute assault on Dacca. Meanwhile, Indian MIG‐21's struck Dacca airport again this afternoon.

General Farman said Pakistani Sabre jets today shot down two Indian Hunter planes west of Dacca. He said that no Pakistani military planes had yet been destroyed on the ground.
