The force of the blast left an enormous crater in Beirut's port:
PM Diab has asked for help from the international community and promised an investigation followed by justice. Both the U.S. and Israel have pledged to offer assistance. Russia is sending a mobile hospital and rescue unit. Among the 100+ dead was top Christian party official Nizar Najarian. Hundreds are still missing - some may still be buried under the rubble. Over 4,000 were injured, and up to 300,000 Lebanese have been left homeless.
