The demonstrators in a statement also condemned the silence of the international community on the aggression against Yemen and considered the United Nations to be an accomplice with the coalition in its war crimes against the impoverished country, Al-Alam reported.
The statement further stressed the need for taking revenge on the enemy for killing innocent civilians.
It praised the Yemeni army and Popular Committees for their operations against the aggressors and targeting the depth of the enemy territory.
In other news, activists projected pictures of coalition warplanes killing Yemeni children on the BBC TV building in London.
They also projected the names and photographs of Yemeni children killed during the US-Saudi aggression.
The activists called for an end to the aggression on Yemen and blockade of the country and demanded that Britain stop its arms sales to Saudi Arabia.
Enjoying complete arms, logistical, and political backing from the United States and Britain, Saudi Arabia led many of its allies in a 2015-present invasion of Yemen.
The war has been seeking to crush the popular Ansarullah resistance movement and reinstall the former Riyadh-friendly government.
The war and the coalition’s siege of Yemen has killed hundreds of thousands of Yemenis and turned the entirety of Yemen into the scene of the world’s worst humanitarian crisis.
