At 04:44 on 17 May 2021, government au- thorities from the Republic of Zirta re- ceived communication from the ‘New Petra Circle’ (NPC) terror group that a diesel-powered submarine (Kilo-class) belonging to the navy of the Federal Republic of Parousia had been hijacked in the Zirtian harbour city of Plimsolla. Parousian officials confirmed to Zirtian authorities that they had lost direct communication with the captain of the Skulla-class submarine PK216. The NPC, which was based in Parousia and had been known to violently oppose the Parousian government, stated that 20 crew members on board PK216 were members of the group and the remaining 30 submariners had been placed in the holding bay.
