People in the area have been describing what they saw.
Adam Fisher, who works nearby, said there was "a huge explosion".
"Everyone went to our work car park to see what was happening," he said.
"Our building is adjacent to the apartment complex - immediately an inferno [was] visible, huge smoke cloud billowing, people screaming and people frantically calling for emergency services."
