Israel's air force claims to have neutralized a drone that was allegedly fired from Yemen early on Sunday.
The drone is one of several that Yemen has attacked Israel with since Tuesday, when the Houthi rebels there threatened to escalate attacks in support of Palestinians after Israel's renewed attacks in Gaza.
In parallel, media controlled by the Iran-backed Houthi movement accuse the USA of having attacked the airport in the port city of Hodeida.
On Wednesday, the US Central Command confirmed "continuous operations" against the Houthi movement. President Donald Trump said the same day that the movement "will be completely destroyed".
