On 12 May 2019, four commercial ships were damaged off Fujairah's coast in the Gulf of Oman. The ships included two Saudi Arabian registered oil tankers, a Norwegian registered oil tanker, and an Emirati registered bunkering ship. The ships were anchored on the United Arab Emirates territorial waters for bunkering in Port of Fujairah. The Ministry of Foreign Affairs of the United Arab Emirates reported that the ships had been subject to a "sabotage attack". The United Arab Emirates launched a joint investigation probe with United States and France. The initial investigation assessment determined that 5-to-10-foot (1.5 to 3.0 m) holes near or below all the ships' waterlines were probably caused by explosive charges.
