Senior U.S. officials are reviewing intensively the continued supply of U.S. arms to Pakistan despite a recently announced ban on such shipments, the State Department said yesterday.

Officials said the review would cover the two Pakistani freighters now carrying U.S.-supplied arms to Pakistan and a quantity of other weaponry being provided to Pakistan by Department of Defense subcontractors.

The State Department announced April 15 that an arms cutoff had been in effect since March 25, when civil strife broke out in East Pakistan.

The department said no additional armaments under military sales provisions would be turned over to Pakistan and that no additional sales licenses would be granted.

The New York Times disclosed Tuesday that two Pakistani vessels, the Sunderbans and the Padma, left New York with arms for Pakistan. It said the Padma left Tuesday. Sen. Frank Church (D-Idaho) sent a letter to President Nixon Tuesday urging interception by the Coast Guard.

State Department spokesman Charles Bray said Tuesday that the arms aboard the two ships had been turned over to the Pakistanis before March 25 and therefore were not covered by the cutoff.
