The international community, including Britain, must load pressure on the Saudi-led coalition in Yemen to avoid further bloodshed, Yemeni activists told a conference in London on Saturday titled Yemen: War, Politics and Human Tragedy.

The world should "assert more pressure on the allied forces. A military solution to the conflict in Yemen will be a disaster, said Abdulrahman al-Hamdi a day after Mohammad bin Salman, Saudi crown prince left the UK having signed further deals with Britain.

The former member of the Yemeni parliament added, Yemen is being destroyed. A nation is dying.

The controversial three-day visit by the Saudi crown prince drew criticism from different sections of the British public, with protesters calling for his arrest over his role in the calamitous war in Yemen.

Before he arrived, thousands had signed an online petition calling on Prime Minister Theresa May to cancel the trip over Saudi Arabia's involvement in the Yemen conflict, which has been called the world’s worst humanitarian crisis and has killed thousands of people and displaced more than 3 million in three years of fighting.

Downing Street  brushing aside calls for an embargo over the kingdom’s role in Yemen’s war announced plans to sell 48 Eurofighter Typhoon jets to Riyadh.

British government made clear that its agenda was to promote commerce and good relations, not to criticize the Saudi government.
