This royal has a heart of gold!

Prince Harry has penned a letter to the Orlando mayor following the Pulse nightclub massacre, where 49 people were killed and 53 were wounded after gunman Omar Mateen opened fire, to offer his condolences for the most deadly terrorist attack on US soil since 9/11.

"I wanted to write and express my most sincere condolences to the people of Orlando after the horrific attack on the Pulse nightclub on Sunday. Having just spent time in Orlando I know what a warm and welcoming community it is. In spite of this senseless act, I have no doubt that the love and friendship of your city will remain strong," he began.

The British heir to the throne also touched on his respect for the first responders.

"I would also like to pass on my deepest admiration to the law enforcement officers who attended the nightclub during the attack for their extraordinary bravery and professionalism. Our thoughts are with the victims and their loved ones at this most difficult of times. You are all in our prayers as you face the days and weeks ahead," he concluded.

Princess Diana's son spent most of May in the city for the Invictus Games, which he founded in 2014.

It's not just Americans grieving during this difficult time.
