"Washington will never achieve any success in its puppetry against Tehran," Velayati said on Monday.
He underlined that the US officials directly accuse Iran of meddling in Yemen while they are indirectly denying the bravery, resistance and self-sacrifice of the Yemeni nation.
Velayati said the Yemeni people have so far succeeded in defeating the Saudi-led coalition and the United Arab Emirates.
On December 14, US Ambassador to the UN Nikki Haley presented what she claimed to
be "undeniable" evidence, including the allegedly recovered pieces of a Yemeni missile, saying it proved that Iran was violating international law by giving missiles to the Houthi Ansarullah movement. The Houthis have been fighting back a Saudi-led aggression with allied Yemeni army troops and tribal fighters since March 2015.
A few days later, she said that the UN Security Council could strengthen the provisions in Resolution 2231, which was approved in July 2015 to endorse the multilateral nuclear deal with Iran, or adopt a new resolution banning Tehran from all activities related to ballistic missiles.
Velayati made the remarks a day after Chairman of the Iranian Parliament's National Security and Foreign Policy Commission Alaeddin Boroujerdi said US President Donald Trump's efforts to demonize Iran by accusing the Islamic Republic of supplying ballistic missiles to Yemen’s Ansarullah fighters was futile and an example of "beating the air."
"Trump is making desperate efforts to portray a negative image of the Islamic Republic of Iran and I believe these measures are [like] beating the air," Boroujerdi said.
