Democratic presidential front-runner Hillary Clinton on Wednesday condemned the ballistic missile tests reportedly carried out by Iran over the last two days, and said Iran should face new sanctions as result.

"I am deeply concerned by reports that Iran has tested multiple missiles, which it claimed were stamped with words declaring that 'Israel should be wiped from the pages of history,'" Clinton said in a statement.

"This rhetoric is repulsive and has no place in the community of nations, and as president I will continue to stand with Israel against such threats," she added. "Iran should face sanctions for these activities, and the international community must demonstrate that Iran's threats toward Israel will not be tolerated."

Clinton's stance is somewhat tougher than that of the White House, which after two days says it is still trying to confirm reports of missile testing. The White House has said new unilateral sanctions are possible, but said it is not ready to announce anything yet.

The White House has also said asking for more multilateral sanctions at the United Nations is also possible.

Clinton, however, did not waste time, saying the missile tests are a "blatant violation of Iran's U.N. Security Council obligations, and such violations must have consequences."

Clinton, who has voiced support for the Iran deal while out on the campaign trail, called for the U.S. on Wednesday to "address Iran's destabilizing activities across the region, while vigorously enforcing the nuclear deal." She also said the U.S. should "hold Iran to its promise" to help locate and bring home Robert Levinson, a retired FBI agent who disappeared in the country nine years ago Wednesday.

"We cannot rest until he is reunited with his family," Clinton concluded.

According to reports early Wednesday, Iran carried out two ballistic missile tests as a warning to Israel just days after the United States criticized the nation for similar tests on Tuesday. Vice President Joe Biden is currently in Israel on a two-day trip.

In response, the Republican National Committee took aim at what it called "The Clinton-Obama nuclear deal."

"The fact that this agreement gave away important leverage on their missile program while never ultimately blocking Iran from obtaining an atomic bomb underscores how reckless and misguided the Clinton-Obama foreign policy really is," RNC spokesman Michael Short said in a statement.
