Iran has resumed transferring funds to Hamas, a senior defense source told Walla! News Sunday, after nearly two years of estrangement between the two terror regimes. The transfers resumed shortly after Operation Protective Edge in Gaza ended in August, the source said. The sources were unable to elaborate on the exact monetary amount transferred to Gaza, but he said it was "significant" - and that Iran is also actively pledging support for terror groups along Israel's southern border to keep fighting against the Jewish state. Moreover, Iranian money will help Hamas arm itself with more advanced weaponry, after much of their arsenal was destroyed during Protective Edge and due to Egypt's war on terror in the Sinai significantly hindering Hamas's arms supply. Hamas's other arms suppliers are tiring of the group, he added, noting "even Sudan is not as much of a main waystation as it used to be." The senior defense official said that the organization's "military wing," the Al-Qassam Brigades, is back to making its own rockets, and also has increased the rate of "test launches" into the Mediterranean Sea. "Hamas is back to making rockets at a rate greater than in the past, but since its members do not use standard and quality materials, assembly line workers are required to conduct experiments to see if they work," he added. "They launch them into the sea as part of the experiment, but also to create deterrence against Israel. To show that they have quietly built up their power again." Iran was once a stronger supporter of Hamas, but the two have been at odds over the uprising against Syrian President Bashar Al-Assad. As a result of Hamas’ refusal to support Assad in the uprising, an angry Iran reportedly stopped supplying the terror group with weapons. Nevertheless, the two sides have been getting closer in recent months. The speaker of the Iranian parliament, Ali Larijani, recently boasted that Iran provided Hamas with the technology it has used to rain down rockets on Israel from Gaza, and Hamas later thanked Iran for providing the group with the rockets. Following the Hamas’s delegation visit to Tehran, some Palestinian media outlets had reported that Saudi Arabia had called certain Hamas officials to voice its displeasure with the visit. Hamas officials, however, subsequently denied the reports, according to Turkish media outlets.
