Background: Operations have been going on to clear Haiphong Harbour, North Vietnam, and other North Vietnamese ports of mines, laid by the United States Navy ships in an attempt to blockade ports in May last year.
The minesweeping operations were part of the ceasefire agreement. The U.S. Defence Department has released this film of the operation in progress.
Minesweeping by newly developed aerial techniques is continuing in three areas, including the main Haiphong shipping channel. But many of the US mines have been destroyed by their own self - destruct mechanisms.
Minesweeping devices towed by helicopters detonate acoustic mines by imitating the sound of a moving ship. Others saver the cables of moored mines.
Last week the first foreign cargo vessel for sometime tied up at haiphong Harbour - although American officials said ships approached Haiphong at their own risk.
