A UK-drafted resolution aimed at pressuring Iran over alleged weapons supplies to Yemeni fighters has failed at the UN Security Council.
Haley did not specify what kind of action could be taken.
President Hassan Rouhani on Wednesday said Iran is ready to discuss regional security issues with its Gulf Arab neighbours as long as foreign powers are kept out of any potential talks. "What I can say is it doesn't help", Haley said.
"That just validated a lot of what we already thought, which is Iran gets a pass for its unsafe and illegal behavior", Haley said.
Iran's mission to the United Nations accused the U.S. and Britain of pushing an "unwarranted draft resolution" to advance an anti-Iran political agenda and "categorically" rejected allegations of arms transfers to Yemen.
The Iranian top diplomat further denounced a recent United Nations Security Council resolution against Yemen as "an ugly show" and said the UNSC, which is supposed to protect peace and security, has turned into an organization supporting "child killers".
Bolivia also voted no and China and Kazakhstan abstained.
"We don't have any illusions with regard to Iran's policy towards Israel, Iran's role in the region. and also what they do in terms of constructing ballistic missiles", the diplomat said.
Following the Russian veto, the Security Council unanimously adopted a technical resolution which renews the current arms embargo without any reference to Iran. "What we're trying, and have to do.is to actually make these points even clearer than in the past".

In a televised interview aired on February 5, Zarif urged Saudi Arabia and the United Arab Emirates to stop war in Yemen and disintegration of the country.
The unanimous vote followed a Russian veto of a UK-drafted text that contained language of Iranian "non-compliance" with the United Nations sanctions regime against individuals and entities deemed to be engaging in or providing support for acts that threaten the peace, security or stability of Yemen.
The UN panel that examined rocket fragments that had been recovered from Saudi Arabia found that they had markings showing that they had been manufactured in Iran.
