Israeli Prime Minister Benjamin Netanyahu has pointed the finger at Iran for last week’s explosion on board an Israeli-owned cargo ship in the Gulf of Oman.

“This was indeed an operation by Iran. That is clear”, Netanyahu told Kan Radio on Monday.

When asked whether Israel would retaliate for the incident, Netanyahu repeated previous statements about his drive to keep Iran from developing nuclear weapons.

Netanyahu’s comments come a day after Israeli Defense Minister Benny Gantz asserted that Iran could be responsible for the explosion, which caused several holes in the port and starboard sides of the Israeli vessel flying under the Bahamian flag. The latter was subsequently identified as the MV Helios Ray. The blast did not disable the vessel or cause casualties but caused the vessel to anchor in Dubai for repairs on Saturday.

“We need to continue investigating. The Iranians are looking to harm Israelis and Israeli infrastructure. The proximity to Iran leads to the assessment that there is a likelihood that this is an Iranian initiative. We are committed to continuing to check”, Gantz said.
