Mindanao and South Sulu area (Palawan inc.) on high alert due to unspecified security threat. Is this credible, or should we simply be keeping our wits about us - as we should usually do!
Philippines has 7, 107 and is grouped into 3 major region, Luzon Visayas, and Mindanao.
South Sulu is on the south most, tip most part of Mindanao. Palawan is facing the Sulu Sea but it's not really close to Sulu, same as Philippines really not that close to China although it's facing the south china sea.
This is not to disregard the warning, but sometimes things are blown out of proportion.
But for foreigners peace of mind, you can just avoid travelling to the Mindanao area. Palawan is okay over 3 years ago
