Pope Francis described the “homicidal folly” of the shooting.
The Islamist militant group, Daesh, have claimed responsibility for the attack, however, they did not specify whether they were behind the attack or simply inspired it.
All flags on federal buildings are now being flown at half mast until sunset on Thursday out of respect for the victims.
The Orlando attack is the most deadly shooting in US history, having surpassed the 2007 massacre at Virginia Tech where 32 people were killed.
The injured are being treated in Orlando hospitals, with urgent appeals being made for people to donate blood.
