Petronas Towers
One possible target of the Malaysian terrorist plot (masterminded by Khalid Sheikh Mohammed) would be the Petronas Towers in Kuala Lumpur, the world's tallest buildings from 1998 until 2004. These potential Malaysian Islamist's connections with Badat and Al-Qaeda were uncovered just a few days after MH370 disappearance. The link was discussed by British media in 2014.
