Qatari Foreign Ministry has filed a new complaint to the United Nations, reporting a second violation of its airspace by a United Arab Emirates (UAE) jet in recent weeks, RIA Novosti reported quoting the ministry.

The "military airlift", which was travelling from the UAE to Bahrain, entered the airspace of Qatar on the morning of January 3 "without prior authorisation", Qatar's foreign ministry said in a statement on Friday. 

Sheikha Alia Ahmed bin Saif Al Thani, Qatar's UN representative, submitted a letter of complaint to Antonio Guterres, the organisation's secretary-general, in light of UAE's repeated infringement upon Qatar's sovereignty, the statement noted. 

"[The] threat to the safety of its [Qatar's] borders and territories is evidence of the UAE authorities continuing their approach to violating international law, conventions, charters and international norms," it added. 

In early June, Saudi Arabia, the UAE, Egypt and Bahrain all abruptly severed diplomatic and trade ties with Qatar, accusing Doha of supporting "terrorism".

The Arab quartet threatened to expand their embargo on Doha if it failed to accept a long list of demands, including the closure of the Qatar-funded Al Jazeera television.

Qatar has strongly denied the accusations.
