DAMASCUS, Feb 1 (Reuters) - A high-level delegation from Hamas arrived in Tehran early on Sunday as part of a regional push to reinforce support for the Palestinian group after the Israeli invasion of Gaza, a Hamas official said.
The delegation, headed by Hamas leader Khaled Meshaal, will later meet Iran's Supreme Leader, Ayatollah Ali Khamenei, and President Mahmoud Ahmadinejad, Izzat al-Rishq told Reuters by telephone from Tehran.
Hamas was in close contact with Iran, its main backer along with Syria, during the 22-day Israeli offensive against Gaza, which was halted last month, with the two sides declaring separate ceasefires.
Hamas views the war as resulting in regional diplomatic gains for the group, with Turkey criticising Israel and Qatar convening a high profile meeting with the participation of Hamas that supported Hamas's objectives.
