  In Noor (2007)[Muhammad Aslam Noor, New iterative schemes for nonlinear
equations, Appl. Math. Comput. 187 (2007) 937-943], proposed an algorithm
namely \textbf{Algorithm 2.4} and established a proof to show cubic
convergence. The presented proof is wrong. In this article, we show that
\textbf{Algorithm 2.4} is not cubically convergent.
