Shahar Peer scored a sensational 6-2 7-5 victory over top seed Caroline Wozniacki at the Dubai Championships, sparked a security problem in the process.

The Israeli athlete was controversially denied entry into the United Arab Emirate nation 12 months ago due to her nationality, sparking a human rights debate.

The former soldier has been heavily guarded throughout this week and has played her matches on the outside courts that are easier to protect.

But after defeating 13th seed Yanina Wickmayer, Virginie Razzano and now Wozniacki, Peer is now into the quarter-finals where she is likely to play in the main arena.
