iran test-fired a surface-to-surface cruise missile monday in a drill its navy chief said proved tehran was in complete control of the strategic strait of hormuz, the passageway for one-sixth of the world’s oil supply.

the 10-day naval maneuvers, which are scheduled to end tuesday, were iran’s latest show of strength in the face of mounting international criticism over its nuclear program.

tehran has threatened to close the strait as possible retaliation to new u.s. economic sanctions.

the missile, called “ghader” in farsi — or “capable” — was described as an upgraded version of one that has been in service before.

the official irna news agency said the missile “successfully hit its intended target” during the exercise. an earlier version of the same cruise missile had a range of 124 miles (200 kilometers) and could travel at low altitudes. there were suggestions it could counter the u.s. naval presence in the persian gulf.

french foreign ministry spokesman bernard valero said at a regular online briefing monday that france “regrets the very bad signal to the international community sent by the latest missile tests announced by iran.”

there have been conflicting comments from iranian officials over tehran’s intentions to close the strait of hormuz and u.s. warnings against such an ominous move.

“the strait of hormuz is completely under our control,” iran’s navy chief admiral habibollah sayyari said after monday’s test. “we do not allow any enemy to pose threats to our interests.”

israeli defense minister ehud barak said the iranian exercise was a show of strength intended “to deter the world from continuing sanctions against it.”

barak said at a party meeting that he doubts iran would close the strait because that would only bring harsher international sanctions. israel considers iran an existential threat due to its nuclear and long-range missile program. iran is also a major backer of hamas and hezbollah militants who are fighting israel.

the west fears iran’s nuclear program aims to develop weapons — a charge tehran denies, insisting it is for peaceful purposes only.

president obama has signed a bill that applies penalties against iran’s central bank in an effort to hamper tehran’s ability to fund its nuclear enrichment program, although the administration is looking to soften the impact of those penalties because of concerns that they could lead to a spike in global oil prices or cause economic hardship on u.s. allies that import petroleum from iran.
