The fate of refugees in Europe has gripped the world’s attention following the publication of the image of the body of one victim: a 3-year-old Syrian boy washed up on a Turkish beach.

When confronted with this latest “viral” image to come out of the Syrian conflict, many people have expressed shock, horror, grief and anger. And many have also tried to help.

Migrant Offshore Aid Station, a charity that runs a fleet of rescue boats to save refugees at sea, told the Guardian that their donations had increased 15-fold in the 24 hours since the photo was published. Dozens of independent online fundraising efforts sprang up overnight, and calls to give or sign petitions began to trend on Twitter and Facebook.

But who to give to?

There are many well-established charity organizations helping the thousands of migrants flooding into Europe, most of whom are fleeing violence in Syria and Afghanistan or the brutal oppression of Eritrea’s dictatorship. The big charity groups are well-known: UNHCR, Unicef, Médecins Sans Frontières/Doctors Without Borders, Oxfam, the International Red Cross and Save the Children.

But there are other, smaller groups doing incredible work on the ground, every day. Here are six, smaller groups we’ve vetted that you can help right away. Suggest other groups in the comments or in our Facebook chat.

Some suggestions from our reporter on the ground - The White Helmets: Also known as the Syrian Civil Defence, these rescue workers are some of the first to rush in after the bombs land each day. They're credited with saving more than 22,000 lives so far. - Watanili: This group is working to rebuild Syria through a series of small grassroots initiatves. A recent project of theirs, called 'Cinema on the Go,' included using film to combat the effects of trauma on the children there. See more of Dalia Mortada's recommendations here.

As for the bigger organizations, a useful tool to consider when evaluating them is their ranking on independent charity watchdog sites like GuideStar or Charity Navigator which evaluate what percentage of donations go directly toward aid versus overhead, among other factors.

Charity Navigator has a list of highly ranked charities currently helping Syrian refugees. We reached out to them to find out more about they are doing and will update this as we get responses.
