After the May 2014 coup, this became moot. The ruling National Council for Peace and Order (NCPO) restructured the bureaucracy responsible for the region. Enhanced counter-insurgency measures contributed to a significant drop in violent incidents and casualties. In spite of this achievement, the security picture is mixed. Late 2013 witnessed coordinated bomb attacks outside the traditional conflict zone and disquieting evidence of possible militant operations in Phuket. On 10 April 2015, a car bomb on the tourist island of Koh Samui showed some of the hallmarks of militant attacks, and all known suspects in the incident are Malay Muslims. These bombings could indicate a new phase of the conflict, though questions remain about the motivation behind them.
