The exiled Hamas chief broke into tears Friday as he arrived in the Gaza Strip for his first-ever visit, a landmark trip reflecting his militant group's growing international acceptance and its defiance of Israel. Khaled Mashaal, who left the West Bank as a child and leads the Islamic militant movement from Qatar, crossed the Egyptian border, kissed the ground, and was greeted by a crowd of Hamas officials and representatives of Hamas' rival Fatah party. He was also welcomed by a group of Palestinian orphans — children of Gaza militants killed by Israel in recent years — wearing military-style uniforms. (AP Photo/Suhaib Salem , Pool)
