An Iranian warplane has spotted a US aircraft carrier during Tehran's ongoing navy drill in the Persian Gulf, reports IRNA news agency. The US fleet's maneuvers come after Iran threatened to block the oil flow through the Strait of Hormuz.

Tehran's surveillance jet has shot a video and pictures of the American carrier, which was later identified as John C. Stennis. The US Fifth Fleet keeps a military base in Bahrain, while the ship was spotted in the Gulf of Oman after crossing the Strait of Hormuz.

Iranian state TV also showed images of the Iranian exercise, which is taking place in international waters near the Strait of Hormuz - the passageway for one-sixth of the world's oil supply. The US Navy's Bahrain-based Fifth Fleet is also active in the area, as are warships of several other countries that patrol for pirates there..
