As I am sure many reading this thread now know, this week's Flight International (appeared on my doorstep this morning) has this incident on the front page, and a good article inside. In essence they are saying that the PAL A330 crew was carrying out some form of non-precision approach and for whatever reason got a GPWS warning on approach. To their credit they did not dither and immediately instigated a missed approach. During this go-around the aircraft suffered damage possibly from trees and/or power cables. An extremely close shave!
