If you look closely at the map you will see how close Phuket is to the insurgency in the Thai south. You can see where the Thailand/Malaysian border is. In the Pattani (southern Thailand) region, five more people have been killed in the past week. The area was an autonomous Malay Muslim sultanate until 1902, when it was annexed by mainly Buddhist Thailand. This sparked decades of tension that spiralled into a full insurgency five years ago.
The newspapers here in Singapore have followed this all year... pretty scary stuff.
