Bulgarians vote this Sunday, October 25, in a presidential election held amid the spread of Russia's war on Ukraine to the waters off Bulgaria's Black Sea coast, according to Al Jazeera. Polls place acting President Iliana Iotova, 61, and ex-caretaker Prime Minister Andrey Gyurov, 50, as leaders in a race of 27 candidates, according to The Hindu.

The vote has taken on added significance after a series of drone attacks on merchant ships off Bulgaria's Black Sea coast that likely killed some two-dozen international seafarers, according to The Hindu.
