Some sacks had washed up on shore.
The other container with dangerous goods, which holds 1,400 kilograms of lithium batteries, is still unaccounted for.

Most of the containers have been located on the floor of the North Sea, Dutch Authorities said on Monday, January 7, 2019.
Using sonar technology, 220 of the 281 containers have been found, according to the Dutch Ministry of Infrastructure and Water Management.

Efforts to recover the containers could take months.
The Swiss shipping company MSC has agreed to take on all costs for the clean-up and salvage operations.
