Are ancient buildings as important as human lives?

Yemen's war is entering its third month, and on Friday Yemenis woke up to news that five houses in the old city of Sanaa, a UNESCO world heritage site, were allegedly hit by a Saudi-led coalition airstrike (Saudi Arabia has denied the claims). The houses, as well as being historic, were also inhabited and the incident killed five people and injured several others.

Online, there was much mourning for the people - but seemingly just as much for the destroyed buildings. "This heritage bears the soul of the Yemeni people, it is a symbol of a millennial history of knowledge and it belongs to all humankind," UNESCO said in a statement.

Yemenis also poured their hearts out. "I have no words to express my feelings right now after seeing this photo and others on twitter... the legendary Harat al Qasmi in the old city with its beautiful bustan [garden]..." one Yemeni woman wrote on Facebook.
