TRT Arabic TV (Turkey) aired a report on the Pepsi boycott in Lebanon, which came after the local Pepsi representatives changed the bottle caps to blue and white colors, the colors of the Israeli flag. 

Activists interviewed in the report claimed that the two lines in the cap resemble the lines in the Israeli flag, with one of them claiming that the two lines symbolize the Nile and Euphrates River, to which supposedly, Israel intends to expand.

Presenter: "It is well known that the Pepsi logo on caps and bottles features these colors: red, white, and blue. But in Lebanon, Pepsi has provoked anger once again, after the company’s representatives there changed the caps to ones that display the colors and pattern of the Israeli flag.
