Qatar said on Saturday that a second United Arab Emirates (UAE) military jet had violated its airspace, prompting a new complaint to the UN.
According to the authority, the planes were on scheduled flights to a known destination, and this move by Qatar was a severe violation of worldwide law, and an infringement of safety standards.
The incident has come at a time when Qatar, since mid-2017, has been facing a diplomatic and economic blockade by the UAE, Saudi Arabia, Egypt and Bahrain, over accusations of supporting "terrorism". However, Pickart cautioned that USA forces don't routinely monitor the flights and operations of the Qatari air force.
Bahrain's Foreign Ministry also issued a statement saying it "strongly condemns" Qatar over the alleged encounter.
Four UAE-based airlines-Emirates, Etihad, flydubai and Air Arabia-operate flights to Bahrain.
The claim could further escalate tensions between Qatar and the four Arab nations that have been boycotting it for months, among them the UAE, home to the world's busiest global airport.
Qatar has strongly denied the accusations, and is seeking worldwide arbitration in an attempt to end the blockade.
Emirates is the Dubai government controlled, global carrier of the UAE. Qatari authorities have denied the allegations.
Sheikh Abdullah bin Ali Al-Thani, a little-known royal, emerged as a key figure in the dispute between the Gulf states in the weeks after Riyadh and Abu Dhabi cut ties with Doha in June. It was not clear if the talks would touch upon the ongoing crisis.
