(CNN) - At least 100 people died and 4,000 were injured in a massive explosion that rocked Beirut on Tuesday, state media reported, citing the Red Cross.

It is still unclear what exactly caused the explosion. Lebanon's prime minister said an investigation would focus on an estimated 2,750 metric tons of the explosive ammonium nitrate stored in a warehouse.
Planet Lab Inc. satellite images show the magnitude of the damage caused by the explosion, which experts have said is comparable to a small atomic bomb and produced a magnitude 3.3 earthquake.
Reports say the damage occurred for miles around, with the port hardest hit.
"The impact on the economy is massive and the port has practically been erased," Lebanese Economy Minister Raoul Nehme told CNBC Arabia in an interview on Wednesday, adding that it was too early to fully assess the magnitude of the damage to the economy.
