If you happened to be in the city of lights yesterday, you may have noticed the iconic Eiffel tower was errily black - with no light in sight. But after the horrific events that took place in Aleppo, the mayor of Paris Anna hidalgo declared the lights on the Parisian landmark were to be switched off as a symbol of honour to the people of the Syrian city. "This symbolic measure, on a monument recognized the world over, aims to compel the international community to act urgently," Hidalgo explained in a tweet.

Sadly, this isn't the first time this year the Eiffel tower has been used to show solidarity to world events. Back in March, the tower lit up in the colours of the Belgian flag after the Brussels terrorist attack. And then a couple months later in June, the tower was draped in rainbow colours, paying respect to the victims of the Orlando shooting at a gay nightclub.
