DOHA, March 16 (Xinhua) -- Qatar filed a complaint to the United Nations over repeated violations by aircraft of the United Arab Emirates (UAE), the state-run Qatari news agency (QNA) said on Friday.
A UAE military transport aircraft CN-35 overflew the Qatari airspace on March 4, said the letter sent by the Permanent Representative of Qatar to the UN Sheikha Alia Ahmed bin Saif al-Thani.
Qatar described the incident as "a severe violation of international law" that could escalate tension in the region, according to the letter.
The Qatari mission to the UN called on necessary measures to preserve international peace and security by putting an end to these violations.
On March 10, Qatar filed another complaint over the violation of its airspace by a UAE military transport aircraft carrier on Jan. 14 and Feb. 25.
It also complained the violation by a Bahraini military aircraft which overflew the exclusive economic zone of Qatar on Feb. 28.
In June 2017, Saudi Arabia, the UAE, Bahrain, and Egypt severed ties with Qatar, accusing it of supporting "terrorist" groups and aligning itself too closely to their regional rival Iran.
Qatar vehemently rejected the accusations.
