Bollywood actor Hrithik Roshan had a narrow escape from the terror attack on Istanbul's Ataturk Airport that killed 36 people and injured over 145 on Tuesday.

"Missed connecting flight at Istanbul and were stuck at airport. Next flight was next day, but took economy and flew out earlier. Prayers for Istanbul," the 42-year-old tweeted on Wednesday.

"Was helped by the kindest staff at Istanbul airport hours ago. Shocking news. Innocents killed for religion. We must stand united against terrorism," he added.

The attack took place on Tuesday evening when three militants opened fire and later exploded their suicide vests.

Hrithik was travelling from Madrid to Africa with his sons Hrehaan and Hridhaan.
