Rescuers have been combing through the rubble of Beirut port in a search for survivors watched breathlessly by relatives of the missing, while an investigation into the huge blast made its first arrests.
A health ministry official said on Saturday that 21 people are still missing and up to 6,000 are injured, four days after a massive explosion at the port left 158 people dead.
