The tanker, identified as the On Peace, was hit 9 nautical miles (about 17 km) off the Omani port city of Limah, the Omani Ministry of Defence said in a statement on X. The ministry did not attribute the attack to any group, and no claim of responsibility had been made as of Wednesday.
India's Ministry of External Affairs said 17 of the 19 crew members were Indian nationals, and 11 of the 12 injured were Indian. The remaining crew included two Bangladeshi nationals, according to Indian officials. The ministry expressed deep concern over what it called "continuing incidents of attacks on shipping in the region" and reiterated its call for an immediate cessation of such attacks.
The attack is the latest in a series of incidents in the Strait of Hormuz, where security has deteriorated sharply since the United States and Israel began their war on Iran in late February. Iran effectively closed the waterway on February 28 and has frequently attacked commercial vessels that do not use its designated route. Iran has also said it wants to charge ships for passage.
At least seven other incidents involving tankers have been reported in the past week, according to Marisks, a shipping intelligence service. India's government said in July that at least 10 Indian seafarers had been killed since the war began; an Indian sailor was killed in another attack on a cargo ship in the strait in September.
Despite the attacks, Middle East crude exports have risen to pre-war levels, with a seven-day moving average of 18.3 million barrels per day on September 30, compared with about 18 million before the war. However, Brent crude futures rose to $101.51 a barrel on Tuesday, up from $72.48 the day before the war began.
