Are world leaders doing enough to stop the war in Yemen?

Four years of war in Yemen show no sign of relenting - especially from the air.

Saudi-led coalition airstrikes have killed at least 45 people in the past week - including wedding party guests, women and children.

As in previous attacks which have killed large number of civilians, the Saudis have promised to investigate.

And the UN Secretary-General Antonio Guterres has strongly condemned the killings - which have also included the Houthis second in command.

Both the Houthis and coalition leaders are being urged to negotiate peace.

What more can the international community do?
