Thirty years ago today, on April 19, 1995 (March 20, 1995 in the lunar calendar), the explosion of the federal building in Oklahoma City, USA killed 168 people. The federal office building in Oklahoma City, USA was bombed. At 9:04 a.m. on April 19, 1995, in the center of Oklahoma City, USA, there was a loud "boom" sound. Flames soared to the sky, thick smoke billowed, and the sound and vibration spread dozens of miles away. In an instant, one-third of the walls of a nine-story building collapsed, gravel flew away, and many people were bloody and died tragically in the ruins. This is a federal office building, where about 500 government officials and employees usually work. There is a day care station on the second floor, where many employees leave their children at work. Most of the staff were in the office when the explosion occurred. Various cars were parked around the building. After the bomb exploded, the cars caught fire and exploded. Some people were killed or burned to death before they even had time to get out of the car. The explosion affected surrounding buildings and homes and caused varying degrees of damage. Firefighters picked up the young victims in the bombed building, and many were crushed to death in the office. What were carried out by rescue personnel were either corpses or disabled people with mangled flesh and broken limbs. The most miserable are children, some of whom have just arrived in the world, aged between 1 and 7 years old. After the explosion, rescuers rushed to the scene immediately. Many injured people were carried to temporary emergency points set up on the street. Many people driving by took the initiative to stop to pick up the injured. Rescue work is still going on intensively. Officials said this was the most serious terrorist explosion in the United States in 75 years. The FBI concluded based on the blown axle and a crater 8-foot deep and 20-foot diameter that terrorists parked a car containing 1000 to 1200 pounds of explosives downstairs on the north side of the building and then detonated it. The FBI issued an urgent arrest warrant on the same day for three suspected men. On April 21, the FBI ordered the arrest of two suspects in the Oklahoma City bombing. U.S. Attorney General Janet Renault announced on the 20th that the government will reward US$2 million to arrest the suspect. Rescue and search for survivors continue in Oklahoma City. Clinton once again expressed on the 20th that the criminals must be caught. He said the government had sent 200 FBI officials to the scene to solve the case, and Clinton also ordered flags at all federal agencies across the country to fly at half-staff to pay tribute to the victims of the bombing. On April 22, the FBI and police continued their search for suspects in the Oklahoma City bombing. McVeigh, the first suspect arrested, is still being questioned. Peter Nichols, who turned himself in to police on the 21st, was initially thought to be the second wanted suspect because he and his brother James Nichols had been in the same unit as McVeigh and remained close. Police still detained the brothers as ammunition suspects. On April 23, US President Bill Clinton announced a series of new measures to combat terrorism at home and abroad. After attending a memorial service for victims of the Oklahoma City bombing, Clinton said he had ordered Attorney General Janet Reno to chair a high-level review committee to examine all federal office facilities for vulnerability within 60 days. U.S. federal investigators arrested another suspect in connection with the Oklahoma City bombing on the 23rd. So far, U.S. federal investigators have detained a total of four suspects in connection with the Oklahoma City bombing, but the second of the two major suspects wanted by the FBI is still at large. Federal agents arrested the man named David Ignis in San Dibena, California that day in the name of catching deserters. Inigus is now a spy in the military. He is suspected of deserting and participating in the Ohio City bombing. He is currently being interrogated by the FBI but has not been charged. After 16 intense days and nights, late at night on the 5th, the scene of the Oklahoma City bombing in the United States was finally cleared. A total of 165 people have been identified as dead, and 2 people are still missing. Rescuers on the scene believed that due to the huge power of the explosion, the limbs of the two missing persons may have been shattered. There has been no significant new progress in the detection of the Oblast bombing in several days. Suspect McVeigh in custody has still not confessed any confession, while another suspect wanted nationwide is still at large. According to reports, the families of the victims will be allowed to go to the explosion site for the last time in the near future to express their condolences to the victims. Later, the bombed building will be demolished. be
