Kabir Khan's upcoming thriller,Phantom, is a story of how a few Indian commandos become undercover agents, tracking down and killing the four masterminds behind Mumbai's 26/11 attacks.

To track down and kill the masterminds, Kabir Khan travels many countries with his undercover agents in the film, including his lead cast Saif Ali Khan and Katrina Kaif. Amongst the many countries that they shot in, one of them was Lebanon, where they recreated a Syrian refugee camp in the mountains on the border of Syria.

Telling us about it, director Kabir Khan said, "Our crew consisted of 500 extras and involved a large movement of trucks, jeeps and SUVs for taking material there for setting up the shoot.There were these two F-16s that were always circling over our heads while we were shooting.We got worried and asked the locals about them, who told us that these were actually the Israeli Air Force planes who were keeping a tab on our movement there, suspecting us to be some kind of rebel movement. I initially thought that they would be Lebanese Air Force planes, but they turned out to be Israeli planes flying for impunity. We decided to tell Saif about it, but we ensured that Katrina was not made aware of it, so that she would not feel scared."
