China blasts: Casualties as Tianjin shipment blows up

Massive explosions have hit China's northern city of Tianjin, causing at least seven deaths and reportedly injuring some 300 people.
According to Chinese state media, the blasts occurred when a shipment of explosives blew up in the port city at about 23:30 (16:30 GMT).
Pictures and video shared on social media showed flames lighting up the sky and damage to nearby buildings.
Shockwaves could apparently be felt several kilometres away from Tianjin.
The editor of the BBC's Chinese Service, Raymond Li, says all indications are that it is an industrial accident.
The first explosion was followed by another 30 seconds later.
An official Chinese seismic agency said the force of the first explosion was equivalent to three tons of TNT, the second was 21 tons.
Further blasts were subsequently triggered nearby, Xinhua state news agency said.
