The suicide bomber who attacked Mike’s Place in Tel Aviv was a British Muslim—and he had an accomplice, also British. They were apparently planning a double bombing, where the second mass murderer detonates as people flee the scene of the first.

The man who carried out the suicide bombing late Tuesday night at a Tel Aviv beachfront pub was a British citizen, as was an additional terrorist who managed to flee when his explosive device did not detonate.

The British man who managed to escape, after scuffling with bystanders at the pub, was named as Omar Khan Shariff. The police and Shin Bet are requesting the public’s help in locating him.
