The slain deputy chief of Hamas, Saleh al-Arouri, has been buried in the Palestinian camp of Shatila in Beirut, amid throngs of mourners launching volleys of gunfire, Reuters reports.

“Palestine and Lebanon bid farewell today, along with the people of the nation, to strong men who fought battles in all fields and directions,” said Hamas chief Ismail Haniyeh in a statement from outside Lebanon.

Their coffins were draped in Palestinian flags and carried by men wearing green caps with “Hamas” written on the front. Heavy bursts of gunfire rang out for hours.
