Kuwait sharply condemns attacks by Iranian demonstrators on the Saudi Embassy in Tehran, and the Saudi Consulate in Mashhad, an official source at Kuwait's Foreign Ministry said on Sunday. Iranian authorities should shoulder responsibility for protecting the embassy and ensuring the safety of its staff, the source said. Such attacks are a flagrant violation of Vienna Convention that requires States to protect and safeguard diplomatic missions and to ensure the safety of their staff, KUNA quoted the source as saying. The source called on Iranian authorities to abide by all international rules and norms which state the respect of States' sovereignty and non-interference in their internal affairs. In addition, the source reiterated Kuwait's support to all measures adopted by Saudi Arabia to maintain its security and stability.
