LORRY drivers returning to Hong Kong from Shenzhen told of being rocked by the blasts as they made their way back to the territory.
Chin Ying-lam, 40, was heading back to Hong Kong along Lei Kwong Road near Qingshuihe when his lorry was shaken.
''The explosion shook my 40-foot-long container. When I looked around I saw a huge column of smoke in the shape of a huge mushroom billowing up in the sky,'' Mr Chin, 40, said.
Until he saw the column of smoke, he thought there had been an explosion in the nearby government dangerous goods depot, which covers an area as large as the Fanling industrial area.
Mr Chin said that when he arrived at the Man Kam To border checkpoint he was asked by Chinese customs and police officers whether he had heard or seen the explosion.
He said they had no news of what had happened or where the explosions had occurred and wanted to obtain some information from him.
