Some 1,200 people walked from Rotterdam to The Hague on Thursday night to raise money for refugees and displaced people from Syria.

NU reports that the hikers would walk 40 kilometers from the Erasmus Bridge in Rotterdam to the Humanity House in The Hague in the overnight walk on the Night of the Refugee. The participants in the charity walk are sponsored by friends, family and acquaintances and this action has already raised more than 500 thousand euros, according to the Refugee Foundation.

Tineke Ceelen, director of the Refugee Foundation, told NU that she is happy that “our country upholds or tradition of international solidarity. The people in Syrian and neighboring Lebanon, Iraq, Turkey and Jordan sorely need our support.”
