At least 28 commercial ships had been attacked in the Strait of Hormuz in October as of Oct. 23, according to a Reuters tally. The Washington Institute for Near East Policy, which has tracked maritime incidents in the region since 2017, says that is more than in any previous month in its records.
More than 30 very large crude carriers have been damaged since the war began in late February, 11 of them in October. On Oct. 13, the Singapore-registered container ship GFS Pride was hit by an unidentified projectile, caught fire and sank; all 21 crew members were reported safe.

Traffic has dropped sharply. Ship-tracking firm Kpler counted only five commodity vessels crossing the strait on Saturday, Oct. 24, and none on Sunday, compared with 31 the previous weekend. Lloyd's List Intelligence data showed weekly crossings fell 17% in early October.
On Tuesday, Iran's navy said an oil tanker that had switched off its tracking system struck naval mines and caught fire. Iran had earlier claimed to have hit at least four tankers near the strait, a claim President Donald Trump dismissed as invented.
