Background: The United States is continuing its operations in Haiphong Harbour to clear the mines laid by U.S. Navy ships in an attempt to blockade ports in the North in May of 1972.
The clearing of mines from North Vietnamese ports was part of the ceasefire agreement. This film shows this operation underway two weeks ago soon after they had been resumed. The clearing of the harbours had been held up because of a dispute over the release of American POW's. Now that those prisoners have been freed the operations are again being carried out.
Some mines were equipped with self-destruct mechanisms. Others are cleared by minesweeping deices towed by helicopters -- they detonate acoustic mines by imitating the sound of a moving ship, or by serving the cables of moored mines.
There has been a renewed threat that these operations may be curtailed because of a new controversy about the release of nine U.S. prisoners being held by the Viet Cong in Laos.
