Palestinian fishermen prepare their nets on a beach in Rafah in the southern Gaza Strip July 6, 2014. In a move that could harden militants' resolve to confront Israel, the Israeli military said it cut the fishing zone for Palestinian fishing boats off Gaza from six to three nautical miles. Israel also beefed up ground forces along the Gaza frontier on Thursday, a deployment widely seen as sending a message to Palestinian militant groups that an invasion was an option if rocket fire did not stop.
