Explosion heard in Bankmer Bldg., Makati.

Alright, my wife who works for one of the office in Bankmer bldg said that at around 3PM they heard an explosion. This was March 25 (thursday). Apparently, I have not come up with anything on the net about the incident. Seems that it might just be an ordinary explosion.

The weird part, it seems that 2 days ago they were sent home early because of a bomb threat within the bldg. This however, turned out to be just a hoax, but why exactly target Bankmer? Is it because its the election year, and that some terrorist are trying to make the election a failure? Or is it because there is a government office in Bankmer? (I just don't know what dept?)

Either way, I hope nothing more happens.
