Four gunmen, believed to be Palestinian, opened up fire at an outdoor market in Israel on Wednesday, injuring at least 13 people and killing 4. Two of the suspects are in police custody. Officials in Israel noted that the threat of attacks in Israel traditionally heightens during Ramadan, which lasts through July 5. In response to the attacks, entry permits for Palestinians have been frozen until further notice. The terrorist group Hamas applauded the attacks, but did not take credit for the actions of the gunmen.
