Iran's Islamic Revolutionary Guard Corps (IRGC) claimed in a statement that its forces downed an MQ-9 Reaper drone and opened fire on an F-35 fighter jet and another drone that had entered Iranian airspace.

In a statement, the IRGC did not reveal when the incidents took place.

Last night, the US military carried out what it called "self-defence strikes" targeting Iranian missile launch sites and boats around the Strait of Hormuz.

The IRGC warned in the statement that it will retaliate against any ceasefire violations.

"The Islamic Revolutionary Guard Corps warns against any violation of the ceasefire by the aggressive US military, and considers its right to reciprocal response to be legitimate and certain," a statement by the group said according to Iranian state-affiliated media.
