Last week, U.S. Ambassador to the United Nations Nikki Haley accused Iran of supplying missile parts to Houthi rebels.
On Tuesday, Haley said the latest missile launch "bears all the hallmarks of previous attacks using Iranian-provided weapons."
On Wednesday, Iran said it would file a U.N. complaint against the U.S. for its accusations.
