Houston residents react after industrial explosion kills two "All of a sudden there was just a big boom and we thought it was an earthquake," 15-year-old Adrian tells AFP after a large explosion in Houston, Texas, woke him up. The pre-dawn blast at a manufacturing firm scattered debris half a mile (800 metres) away. Emergency services rushed to the scene when a loud blast was heard across much of the Texan city at about 4:15 am local time. SOUNDBITES
