Singapore Foreign Minister Warns of Sea-Borne Terrorism

Reported here:

Foreign Minister George Yeo painted a dark scenario of the devastation that might hit Singapore should terrorists blow up a hijacked tanker in the island's harbour, one of the world's busiest.
"Singapore would, of course, be devastated. But the impact on global trade would also be severe and incalculable," he told Asia's biggest security forum as it wrapped up its annual session in the Laotian capital on Friday.

Pretty much the Standard Warning.
