Ukrainian authorities say they have detained more than 40 alleged members of a terror group in the Black Sea port city of Odesa.
A spokeswoman for the Ukrainian Security Service (SBU), Olena Hitlyanska, wrote on Facebook on April 10 that the suspects had planned a series of terrorist acts in the city during celebrations marking the Orthodox Easter on April 12.
"A large number of weapons and explosives" were confiscated from the suspects, Hitlyanska wrote.
She added that searches were continuing.
Last week, the SBU said it detained three people suspected of involvement in a series of bombings in Odesa, some of them targeting organizations with ties to soldiers fighting against Russian-backed rebels in eastern Ukraine.
Ukrainian authorities blamed those blasts on Russia and the rebels who hold parts of the regions of Donetsk and Luhansk.
