The global stars will be embarking on a tour of Mexico and America next year and their managers are said to be taking no risks when it comes to their safety.
The Mirror quotes a security source as saying: "They are the biggest boyband in the world. If their bosses say we need guns, then we have to get guns. They will be travelling to some dangerous areas in the world."
The source also spoke about the threat of a kidnap plot for members Harry Styles, Louis Tomlinson, Liam Payne, Niall Horan and Zayn Malik.
They added: "There are lots of threats - the worst possibility is a gang will want to kidnap them. But that won't be allowed to happen.
"The group's security guards have all had to get social security cards and ID cards for America and Canada. And they may bring in armed guards who they have worked with before in Mexico."
However, a spokesperson for the band is quoted as saying that the social security cards are "not part of an attempt to gain gun licences in the States", while adding: "I have no idea about Mexico."
