Haq noted that the UN "cannot confirm" the information about the drone attack on the Kremlin.
"We strongly reiterate our call on all parties concerned to refrain from any rhetoric or action that could lead to a further escalation of the conflict," he stressed.
On the night of May 3, the Kyiv regime attempted to strike with unmanned aerial vehicles at the Kremlin residence of the president. Russian President Vladimir Putin was not injured in the attack, the Kremlin said.
Moscow regarded this incident as a "planned terrorist act and an attempt on the President of the Russian Federation." The Kremlin said that Russia reserves the right to take retaliatory measures.
Ukrainian President Volodymyr Zelensky, who is on a visit to Finland, claims that Kyiv is allegedly not involved in the attempted drone attack on the Kremlin.
