芬兰官员证实，一艘俄罗斯军舰周三在芬兰湾遭到袭击，不过外界对这起袭击所知甚少。
Finnish officials have confirmed that a Russian warship was attacked in the Gulf of Finland on Wednesday, although little is known about the strike.
乌克兰国家安全局（SBU）表示，其目标是“纳罗-福明斯克”号军舰，这是针对波罗的海沿岸俄罗斯乌斯季卢加石油出口码头的更大规模无人机行动的一部分。
Ukraine's SBU security service said it targeted the ship Naro-Fominsk as part of a broader drone operation against Russia's Ust-Luga oil export depot on the Baltic coast.
据信这是乌克兰无人机首次在波罗的海对民用航运开放的区域内袭击俄罗斯船只，这起袭击引发了外界对乌克兰是否会扩大打击范围的疑问。
The attack, thought to be the first time Ukrainian drones have attacked a Russian ship in an area of the Baltic Sea open to civilian maritime traffic, has raised questions about whether Ukraine could expand its strikes.
赫尔辛基一直是基辅最紧密的欧洲盟友之一，芬兰官员称这起事件是俄罗斯持续全面战争的直接结果。
Helsinki has been one of Kyiv's closest European allies, and Finnish officials have described the incident as a direct result of Russia's continued full-scale war.
芬兰军方几乎没有透露这起事件的细节，但袭击似乎发生在距芬兰海岸一段距离的一处狭窄水域。
Finland's military has given few details of the incident, but it appears to have taken place in a narrow stretch some distance from the Finnish coast.
芬兰外交部长埃利娜·瓦尔托宁坚称，波罗的海局势依然稳定安全，对海上交通不存在任何形式的威胁。
The country's Foreign Minister Elina Valtonen was adamant that the situation in the Baltic Sea remained stable and safe and that there was no threat of any kind to marine traffic.
据了解，芬兰国防官员已向基辅强调，芬兰湾是一条相对狭窄的水道，有油轮和民用船只通行，海底还铺设着数据电缆。
Defence officials are understood to have stressed to Kyiv that the Gulf is a relatively narrow waterway used by oil tankers and civilian vessels, and is also home to subsea data cables.
乌克兰国家安全局称这艘俄罗斯军舰是“布扬-M”型小型护卫舰，搭载“口径”和“缟玛瑙”巡航导弹。还有未经证实的报道称俄军战斗直升机被摧毁。
Ukraine's SBU described the Russian ship as a Buyan-M type small corvette that carried Kalibr and Oniks cruise missiles. There were also unconfirmed reports of Russian combat helicopters being destroyed.
与芬兰湾接壤的爱沙尼亚，其国防部长汉诺·佩夫库尔对公共广播机构ERR表示，该舰于周三约05:30（格林尼治时间03:30）被击中，但没有说明袭击方式：“我们知道之后船上有烟雾冒出。船本身返回了圣彼得堡方向。”这艘俄罗斯海军舰艇的伤亡或受损程度仍不清楚，而莫斯科很少提供此类细节。
Martin Herem, the defence minister of Estonia, which borders the Gulf, told public broadcaster ERR that the ship was hit at about 05:30 (03:30 GMT) on Wednesday but did not say how it was attacked: "We know that smoke came from the ship afterwards. The ship itself went back towards St Petersburg." The extent of casualties or damage sustained by the Russian navy ship remains unclear, and Moscow rarely gives such details.
军事分析人士、黑鸟监测组织联合创始人埃米尔·卡斯特赫尔米表示：“波罗的海舰队迄今为止一直未受触动，但乌克兰似乎曾有一个可乘之机，他们试图加以利用，这可以理解。”
"The Baltic Sea fleet has been untouched up to this point but there seemingly was a window of opportunity for Ukraine and they understandably tried to use it," said military analyst Emil Kastehelmi, co-founder of the Black Bird monitoring group.
自俄罗斯2022年2月发动全面入侵以来，俄罗斯和乌克兰的船只多次在 Black Sea 成为攻击目标，但尽管此次对波罗的海一艘船只的打击是前所未有的，卡斯特赫尔米告诉BBC，他并不认为这是一次严重的升级。
Russian and Ukrainian vessels have been repeatedly targeted in the Black Sea since Russia's full-scale invasion began in February 2022, but even though the latest strike on a ship in the Baltic is unprecedented, Kastehelmi told the BBC he did not consider it a serious escalation.
乌克兰无人机经常从乌克兰北部发射进入俄罗斯。据信，乌斯季卢加码头的好几个储油罐在周三夜间遭到袭击，隔着边境在爱沙尼亚可以看到港口的火光。
Ukrainian drones are regularly launched into Russia from northern Ukraine. Several storage tanks at the Ust-Luga terminal are thought to have been hit overnight on Wednesday and fires at the port were visible over the border in Estonia.
赫雷姆说，乌克兰无人机从午夜到大约06:00袭击了乌斯季卢加地区，大多数飞行靠近爱沙尼亚边境，但仍处于俄罗斯领空内。
Herem said Ukrainian drones attacked the Ust-Luga region from midnight until about 06:00, mostly flying close to the Estonian border but still in Russian airspace.
他补充说，有一架无人机从拉脱维亚短暂进入爱沙尼亚领空，然后飞向俄罗斯。
He added that one drone had entered Estonian airspace briefly from Latvia and then headed towards Russia.
当时，驻扎在波罗的海国家的北约飞机正在空中，但赫雷姆说，击落这些无人机被认为并不安全。
Nato aircraft based in the Baltic states were in the air at the time, but Herem said it had not been considered safe for them to destroy the drones.
乌克兰外交部发言人赫奥尔希·蒂赫伊周三晚间表示，莫斯科关于基辅利用波罗的海国家领空攻击俄罗斯的指控“毫无根据”，不过他承认“当俄罗斯使用电子战手段将无人机从其领空转移时，可能会发生意外事件”。
Ukrainian foreign ministry spokesman Heorhiy Tykhyy said late on Wednesday that Moscow's allegations that Kyiv had used the airspace of the Baltic states to attack Russia were "baseless", although he acknowledged "incidents might occur when Russia diverts drones from its airspace using electronic warfare".
