DACCA, Pakistan, July 27 — Pakistani authorities charged today that an Indian artillery barrage killed five civilians and wounded 13 in the district capital of Comilla in East Pakistan.

Comilla, which is close to the Indian frontier, was reported shelled last week and Pakistani officials said one civilian was killed. Shelling across the frontier occurs almost daily and has resulted in many disputes between the Indian and Pakistani Governments.

Meanwhile, military authorities here discounted the effectiveness of the two‐week‐old offensive being conducted by Bengali separatists. Handbills posted in Dacca have warned the population to evacuate the city by Aug. 1 to avoid injury in the coming clashes between guerrillas and the Pakistani army.
