"The shock wave just blew through our apartment. It blew out the glass, it blew out the doors, it knocked out the power," said Vafa Anderson, a teacher at an international school who lives less than 2 kilometers (about a mile) from the explosions' epicenter.
Anderson said he was awakened by the first blast and was looking out the window when the second went off, sending a "huge mushroom cloud" into the sky.
