保加利亚政府周一表示，已向欧盟和北约请求技术援助，以调查其黑海专属经济区内两艘商船遭受的无人机袭击事件。
Bulgaria has requested technical assistance from the EU and NATO to investigate drone attacks on two commercial vessels in its exclusive economic zone in the Black Sea, the government said Monday.
据保加利亚通讯社报道，总理卢门·拉德夫在致欧洲理事会主席安东尼奥·科斯塔、欧盟委员会主席乌尔苏拉·冯德莱恩和北约秘书长马克·吕特的信中，敦促盟国将此次调查置于优先位置。
Prime Minister Rumen Radev urged allies to prioritize the investigation in letters to European Council President Antonio Costa, European Commission President Ursula von der Leyen and NATO Secretary General Mark Rutte, according to the Bulgarian News Agency.
拉德夫表示，保加利亚强烈谴责对商业航运和民用船员的军事袭击，并决心查明责任方。
Radev said Bulgaria strongly condemned military attacks against commercial shipping and civilian crews and was determined to identify those responsible.
保加利亚当局还向欧洲海事安全署请求援助，因未能找到可能确定袭击中所用无人机来源的无人机碎片。
Bulgarian authorities also requested assistance from the European Maritime Safety Agency after failing to locate drone debris that could establish the origin of the drones used in the attacks.
所请求的支持将有助于检查调查过程中收集的实物证据、卫星数据和其他信息。
The requested support would help examine physical evidence, satellite data and other information gathered during the investigation.
拉德夫称，索菲亚将采取一切必要步骤，以确凿证据确定责任方，并强调欧盟通过欧盟委员会及其机构提供技术支持的作用。他补充说，保加利亚也正就盟国援助与北约保持联系。
Radev said Sofia would take all necessary steps to establish responsibility beyond doubt, highlighting the EU’s role in securing technical support through the European Commission and its agencies. Bulgaria is also in contact with NATO regarding allied assistance, he added.
拉德夫表示，一旦确定肇事者，索菲亚将根据国际法采取所有可用的外交和法律措施。
Once the perpetrator is identified, Sofia will pursue all available diplomatic and legal measures in accordance with international law, Radev said.
