Traffic Accident involving 14 vehicles

Today I heard that there's an accident at the Puchong Jaya big traffic light juntions, just before IOI mall, that's causing huge jams everywhere.... I have no idea how bad it was till I search online...
Here's some photos from lowyat.net







I really don't know what to say about this
This accident is really bad....
It's a freaking trailer "lost control" ( according to berita harian)
