This is the heart-stopping moment a group of tourists had a very close call with probably the world's most peaceful silverback gorilla.<br /><br />The footage shows the huge ape walking towards the tourists and passing by them as if he did not notice their presence.<br /><br />The tourists can be seen turning their backs to the gorilla in order to avoid exchanging looks with the animal.<br /><br />The filmer writes: ''Time seemed to stand still but race at the same time. <br /><br />''I think I may have held my breath for most of the time. <br /><br />''I couldn’t believe we were so close and that they were so content. <br /><br />''It was a once in a lifetime experience and I can’t think of anything else that hits the mark.''<br /><br />The clip was filmed in Rwanda in May 2017.
