The UAE on Monday accused Qatari fighter jets of intercepting passenger flights operated by Emirati national carriers to Bahrain, as a months-old feud between the Gulf states continued to escalate.

The Qatari government said the allegation was “completely false”.

The UAE’s state news agency said one flight was a regular, scheduled service by an Emirati national carrier to Manama, on a known flight path that met all the required and internationally recognised approvals and permits.

“The General Civil Aviation Authority received a message from a national carrier on Monday morning that an aircraft on a routine flight to Manama was intercepted by Qatari fighter jets in a flagrant and serious threat to the safety of civil aviation and a clear violation of international law,” it said.
