Iranian Foreign Minister Mohammad Javad Zarif has categorically rejected the anti-Tehran claims raised by Saudi officials, saying such allegations are against international laws.

Speaking in a Tuesday phone conversation with Britain’s Foreign Secretary Boris Johnson, Zarif lashed out at Saudi Arabia for its provocative moves in the region.

He also rejected the false and dangerous claims raised by Saudi officials, and stressed that such allegations are against international laws and the UN charter.

Zarif and Johnson also conferred on bilateral ties between Tehran and London as well as regional and international issues.

The Iranian top diplomat’s comments came after Saudi Crown Prince Mohammed bin Salman accused Iran of “direct military aggression” which could be an “act of war.”

Saudi air defence forces intercepted a ballistic missile on Saturday fired toward the capital, Riyadh, from across the border in Yemen. The Kingdom’s officials are accusing Iran of supplying the missiles to Yemen’s Houthi fighters, while Iran denies such allegations.
