Picture: What was Paris Hilton doing in Beirut?

Hollywood babe and millionaire heiress Paris Hilton tweeted a picture on March 7th, 2012 with a caption that said: "Me in Beirut with the SWAT team. They made me feel very safe during my stay and were awesome guys."
Looking at the picture, it seemed to have been taken outside of Beirut airport...(Just guessing here!!!)
So what was she doing in Beirut?! And how come her trip wasn't covered by the press and media?!
Was Paris' visit just a vacation or was she planning for something in the city?!
