After the regional and internal conflicts broke out in Yemen in 2015, Subay launched the fifth campaign "Ruins" on May 18, 2015, to commemorate the victims of the conflicts and to highlight the catastrophic situation of the country. He often paints in the areas ruined due to the conflicts. Subay painted his first mural in the campaign in an area called "Bani Hawat" located in the suburbs of Sana'a, where an airstrike killed almost 27 civilians, including 15 children.[1][2][29][30]
