Israel has been accused of violating the Gaza ceasefire for the third day in a row. Earlier today, the Israeli navy opened fire on Palestinian fishermen within the six nautical mile limit, injuring two. Meanwhile, Israel opened the Kerem Shalom border crossing, allowing truckloads of humanitarian aid, goods, and building materials to enter the beleaguered Palestinian enclave. The building materials, however, will only be used for private construction projects. Noor Harazeen reports from Gaza. teleSUR
