Security was stepped up across India this past week following a series of bombings in cities across the country. Kumar Datta captures the tension perfectly with this shot of a security officer’s hand. His was one of many standouts in a week of very strong contributions from our readers.

We get a lot of sunset pictures submitted to You Witness but this one from contributor Mohd Saifulnazim Azman in Malaysia takes the cake. The combination of colors, the stark contrast and the tiny silhouettes of runners on the beach make this a truly memorable image.
