The White House cautiously avoided confirming that Iran had carried out a second series of missile tests Thursday, but said Tehran should cease "provocative" acts.
"I don't have our own US government verification that there were any additional tests, but they did test the day before," said Tony Fratto, a White House spokesman.
Iran test-fired more weaponry on Thursday as it continued war games, ignoring global concern over its launch of a broadside of missiles amid efforts to end the crisis over its nuclear programme.
The weapons fired in the Gulf by the naval section of the Revolutionary Guards included shore-to-sea, surface-to-surface and sea-to-air missiles, state television said in Tehran. No details were given on the names of the missiles.
Fratto said that "tests are in violation of, or the expansive use of ballistic missiles are in violation of UN Security Council resolutions."
"We want to see them stop enriching uranium and we'd like to see them stop these provocative tests that only further isolate the Iranian people," Fratto added.
