迪拜/伦敦/华盛顿——伊朗正采用新战术，针对通过霍尔木兹海峡航行的船只，旨在维持油价高位并影响美国中期选举，两名伊朗高级官员说。
DUBAI/LONDON/WASHINGTON - Iran is deploying new tactics to target ships sailing through the Strait of Hormuz as it seeks to keep oil prices high and influence the U.S. midterm elections, two senior Iranian officials said.
自美国和以色列于2月28日对伊朗发动袭击以来，德黑兰一直试图对霍尔木兹海峡施加控制。
Tehran has tried to exert control over the Strait of Hormuz since the U.S. and Israel launched strikes against Iran on Feb. 28.
它限制了该水道的通行，该水道在战争前承载约全球五分之一的石油和液化天然气贸易，以此对华盛顿施加杠杆。
It has restricted passage through the waterway, which carried about a fifth of global oil and liquefied natural gas trade before the war, in an effort to gain leverage over Washington.
其威胁和攻击已大幅削减海峡的交通，推高油价，尽管仍有部分石油继续通过。
Its threats and attacks have severely curtailed traffic through the strait, driving up oil prices, though some oil has continued to transit.
