Donald Trump weighed in on the deadly assault at an airport in Turkey on Tuesday, decrying "yet another terrorist attack."

In his response on Twitter, Trump asked,"Will the world ever realize what is going on?"

"So sad," he added. In a subsequent tweet, Trump emphasized the need to "do everything possible to keep this horrible terrorism outside the United States."

The Trump campaign later released a statement that said, "Our prayers are with the families of those killed and injured in Istanbul. The whole world is stunned and horrified."

The presumptive GOP presidential nominee sparked controversy with his reaction to the Orlando mass shooting earlier this month, tweeting: "Appreciate the congrats for being right on radical Islamic terrorism, I don't want congrats, I want toughness & vigilance."
