Iran's defence minister says the Islamic Republic had tested a new missile, confirming earlier reports, Tasnim news agency quoted him as saying.
Hossein Dehghan said the test did not violate the country's deal on its nuclear programme or the United Nations Security Council's resolution.
"The recent test was in line with our plans and we will not allow foreigners to interfere in our defence affairs," he said.
A US official said Iran on Sunday test-launched a medium-range ballistic missile that exploded after travelling 1010km.

"The recent test was in line with our plans and we will not allow foreigners to interfere in our defence affairs," Defence Minister Hossein Dehghan said, according to Tasnim news agency .
"The test did not violate the nuclear deal or the (UN)resolution 2231," he said.
Iran's Foreign Minister Mohammad Javad Zarif neither confirmed nor denied the US report, but said on Tuesday that Tehran would never use its ballistic missiles to attack another country.
The UN Security Council resolution, adopted in a deal to curb Iran's nuclear activities, "called upon" Iran to refrain from work on ballistic missiles "designed to" deliver nuclear weapons. Critics say the language does not make this obligatory.
Tehran says it has not carried out any work on missiles specifically designed to carry such payloads.
