Expressing their outrage, world leaders denounced terrorism and condemned the recent attack at Istanbul's Ataturk airport in Turkey that killed at least 36 people and injured several more in a suicide bomb blast.

Even as details about the tragedy unfold, several political figures took to social media to share their grief. Here are some of the tweets:

"Attack in Istanbul is inhuman & horrific. I condemn it strongly. My thoughts are with bereaved families. May the injured recover quickly," Indian Prime Minister Narendra Modi tweeted.

Congress vice president Rahul Gandhi also condemned the attack. "My prayers are with the families of the victims & the ppl of #Istanbul," Gandhi tweeted. "Shocked &deeply saddened by news of yet another terror attack in #Istanbul. Strongly condemn this cowardly attack on innocents," he said in another tweet.

United States presidential hopeful Donald Trump also took to the social networking site. "Yet another terrorist attack, this time in Turkey. Will the world ever realize what is going on?," he tweeted. "We must do everything possible to keep this horrible terrorism outside the United States." Soon after, he used the incident to launch a political rhetoric to support his endorsers, the National Rifle Association. "Just waiting for Obama to blame this Turkey Terrorist Attack on Guns again," he tweeted.

Although Obama has not engaged social media yet, the official White House twitter handle and press secretary Josh Earnest released a statement. "The United States condemns in the strongest possible terms today's heinous terrorist attack," said the tweet.

Democratic presidential candidate Hillary Clinton also condemned the incident. She called for the U.S. to "deepen" its "cooperation" with allies in the Middle East and Europe to take on the threat of terrorism. "Terrorists have struck again in the heart of one of our NATO allies—and all Americans stand united with the people of Turkey against this campaign of hatred and violence," she said in a statement. "Today's attack in Istanbul only strengthens our resolve to defeat the forces of terrorism and radical jihadism around the world. And it reminds us that the United States cannot retreat."
