1. Certain movable marine obstacles known as "chains" to"the Soviet authorities
are being laid by naval trawlers along the.eoast Qf the Caspian sea. The'purpose is to protect the-marine oilfields of the Gulf of Baku,'the region
around the island of Artem, and the city of Alyaty_jthirty.,kilometers to the
south of Baku).
2. These so-called "chains" consist of a two to four series of nets, with a'
breadth of two tQ three kilometers. The series toward the outside are equipped
with explosives, which detonate at the least contact. ?These "chains" are con-
structed and laid with the utmost secrecy, by the Soviet Navy,
3. These devices are nearly invisible. Only a few of them are indicated by buoys.
As a result,'vessels navigating in the affected waters have to be'handled by
naval pilots, using secret charts for navigation. When the laying of the new
devices was beginning,*a tanker is reported to have run into one of them by
accident and been sunk.
