Hamas political bureau chief Khaled Mashaal traveled from his base in Damascus to meet with Hizbullah terrorist chief Hassan Nasrallah and other Lebanese leaders in Beirut on Monday.
It was Mashaal's first known visit to the Lebanese capital since the Israel Air Force bombed Hamas offices there during the 2006 Second Lebanon War.
Both Mashaal and Nasrallah avoid appearing publicly in person and keep their movements secret due to fears of assassination.
The two beneficiaries of Iranian largesse met together with several other Lebanese leaders as well. According to the Lebanon National News Agency, Mashaal also met for talks with President Michel Suleiman at the presidential palace in suburban Ba'abda.
Reportedly the agenda included a discussion about the situation in the 12 "Palestinian refugee camps" where former Arab residents of Israel and their descendants have lived since fleeing their homes at the behest of the invading Arab nations during the 1948 war.
Tensions between Hamas and the rival Fatah faction divided the Palestinian Authority territories between the two groups as a result of some of the worst internecine clashes ever seen in Gaza. Ultimately, Hamas seized total control over the region in June 2007, while Fatah retained control over Judea and Samaria.
Those tensions have also begun to simmer under the surface in Lebanon's Palestinian population as well, threatening to spill over into violence among the 400,000 residents of the camps.
