Neighbours Sudoku (Fun With Sudoku #19)

This Sudoku first time I saw in World Sudoku Championship 2009 (Puzzle L5). The difference in this from the WSC puzzle is that in the WSC puzzle both the diagonal should also 1 to 9 but in this puzzle, there is no diagonal constraint. This puzzle I created for the Indian Team practice and now I am re-publishing this Sudoku as the 19th Sudoku in the Fun With Sudoku Series. Can you solve this medium-level Neighbours Sudoku Puzzle?
