Daily League - Arrow Sudoku

At the Daily League that was started on Facebook, today we have the Arrow Sudoku by Bastien V J.

Each row, column and region must contain the digits from 1 to 9.
Within an arrow, the digit in the circled cell is equal to the sum of the digits on the rest of the arrow.

Classic 2013 - 2

Back to the basics. Today is the time for a classic sudoku.

Fill the grid such that every row, column and 3x3 box contains the digits 1 to 9.

Yes, you guessed is right. I am enamoured by the diagonal symmetry.
