A series of devastating earthquakes have hit southern Turkey and north-west Syria killing at least 56,000 people and injuring many more.

People have been left without shelter in freezing winter conditions. Access to clean water will likely be a challenge, bringing the risk of cholera and other diseases.

DEC charities and their local partners are among the first responders, working with locally-led relief efforts to ensure people have food and clean water.

People need help now. Please donate.
