At least 17 people were killed and around 400 injured in two massive explosions in the northeastern Chinese port city of Tianjin on Wednesday.<br /><br /> Video posted on Youtube showed fire shooting into the night sky.<br /><br /> Chinese media sources said the blasts came from a shipment of explosives but those reports are unconfirmed. <br /><br /> The first explosion happened at around 1130pm local time and was reportedly felt several miles away. The second blast came around 30 seconds later. <br /><br /> Hospitals were reported to be overwhelmed with casualties with the official Xinhua news agency saying around 400 people were injured. <br /><br /> President Xi Jinping demanded that the authorities make “every effort to rescue and treat the injured, and ensure the safety of people and their property.”<br /><br /> The military have been brought in to help control the situation. <br /><br /> Evidence of the strength of the blasts could clearly be measured by the extent of the damage to hundreds of buildings surrounding the industrial complex.
