DACCA, Pakistan, Dec. 8 (UPI) — The rumble of heavy bombing perhaps 20 miles away could be heard in Dacca today, but the city's shops were open and traffic on the streets was heavy.

Three Indian jets struck Dacca airport, shortly after 8 A.M., touching off air‐raid alerts in the capital. Each plane made a single bomb run.

But aside from the sporadic airport raids and the sound of sirens, Dacca itself was very quiet. Trenches were being dug. Vehicles on the street were covered with camouflage paint and mud, and many were festooned with shrubbery.

A total nighttime blackout and curfew is in effect. During a visit to the river port of Narayanganj, about 10 miles to the south, sailboat traffic, could be seen moving on the river. There was no visible sign of bomb damage there.

But on the return trip, destruction cause by bombing over the weekend could be seen in the jute mill area at Adamjeenager. Some Indian bombs were said to have fallen short of their target, a power house, and to have struck in the midst of an area jammed with tin‐roofed shanties. About 300 people were reported to have been killed and about 150 wounded.
