On Tuesday, a massive blast wave in Beirut, Lebanon's capital, killed at least 135 people and wounded 5,000 others.

The impact of the devastating explosion is ongoing: More than 300,000 people's homes were damaged in the explosion, and hundreds have been reported missing, which people fear could raise the death count. The president has called for a two-week state of emergency.

The explosion's exact cause is currently undetermined, but Lebanese officials are pointing to the storage of 2,750 tons of ammonium nitrate, a highly explosive fertilizer, which was kept without safety precautions in the port of Beirut for years. Investigators are looking into possible negligence concerning the ammonium nitrate's storage. There's evidence that Lebanese officials knew about the danger, yet failed to properly act.

Now, anger with the ruling elite in Lebanon is boiling over into calls for revolution.

Even before the blast, economic collapse, due to decades of mismanagement and corruption, was threatening the livelihood of people in Lebanon. In the months prior, the Lebanese pound had dropped to record lows.

Amid the country's economic collapse, the price of basic necessities skyrocketed, exacerbating hunger for many in Lebanon. All of this was coupled with a recent escalation in COVID-19 cases, and hospitals are now packed with victims of the explosion.

In short: Those in Beirut (and Lebanon as whole) desperately need help right now.

Charity Navigator, the charity ranking site, has compiled the following list of organizations to support in the wake of the explosion. Some are secular; others, like Lutheran World Relief and International Orthodox Christian Charities, are religious. As always, make sure to do your own research to see which is right for you.

We've included some of our own picks as well, and will update this list as the list of organizations continues to grow.
