The Iranian government on Wednesday denied supplying weapons to Houthi rebels in Yemen in response to Saudi claims that a missile intercepted over Riyadh on Tuesday was "Iranian-manufactured".
Houthi rebels claimed the attack which they said had targeted the Yamamah palace, the official residence of King Salman.
Saudi Arabia and the US accuse Iran of providing arms and other supplies to the Houthis, which Tehran has repeatedly denied.
"We have no arms link with Yemen," Bahram Ghasemi, a spokesman for the Iranian foreign ministry, told the ISNA news agency on Wednesday.
"The accusation that Iran gives weapons to various groups is rejected and we strongly deny it," he said.
"Yemen is in a blockade and such possibility does not exist anyway."
