In the paper titled “Null Geodesics and Strong Field Gravitational Lensing in a String Cloud Background,” recently, we have studied null geodesics and strong field gravitational lensing of a black hole with string cloud background [1]. References of some equations were missing in the paper titled “Null Geodesics and Strong Field Gravitational Lensing in a String Cloud Background.” Here we add these references. Equations (10), (13), and (22) were originally derived in the following references:
