"Following Russian President Dmitry Medvedev's address, the Ukrainian Foreign Ministry has sent another note of protest over the pollution of the Sevastopol Bay waters," he said.
Kostenko said that an agreement between Ukraine and Russia foresees that in similar cases, Russia should immediately allow a Ukrainian environmental service to take a water sample, however, this had been ignored.
He said that the Ukrainian Foreign Ministry had not released this information earlier in order not to "aggravate the situation" linked to Russian President Dmitry Medvedev's open letter to Ukrainian President Viktor Yushchenko.
He said that since the start of the year, Ukraine had sent 14 notes of protest to Russia over the violation of Ukrainian laws by the Russian Black Sea Fleet.
