No seawater pollution linked to drone-hit ships, authorities say

No seawater pollution has been linked to the incidents involving ships, the Black Sea Basin Directorate in Varna said on its website. 

Seawater samples were collected near Cape Kaliakra and Byala on 23 October. Tests found nitrate nitrogen levels slightly above the permitted limit near Byala, but the elevated concentration could not be linked to the ship incidents. Results for all other parameters tested were within normal limits.
