AMERICAN nationals in the Philippines have been warned anew against traveling to Mindanao following the bomb attack in Davao City on the evening of September 2.

The explosion left 14 people dead and 67 others injured.

"The Embassy has temporarily suspended all official travel to Mindanao. While we have no information that indicates there is a direct threat to US citizens or interests in the Philippines, the Embassy encourages all US citizens to remain vigilant and employ sound personal security measures as you go about your day," a US Embassy advisory read.

It said the embassy has continued to monitor developments on the investigation being conducted on the powerful explosion.

The advisory also reminded US citizens that a state of lawlessness has been declared by the Philippine government and elements of the Philippine National Police (PNP) and Armed Forces of the Philippines (AFP) have been placed on high alert.

"The embassy will continue to monitor the current state of affairs in the Philippines and will release additional messages as needed," it said.

It also reminded US citizens of the most recent Department of State Worldwide Caution, dated March 3, 2016, which indicates there is an ongoing threat of terrorist actions and violence against United States citizens and interests abroad, including the Philippines.

"Extremists have targeted sporting events, theaters, markets, mass transportation systems, including airlines, and other public venues where large crowds gather. Crowded nightclubs, shopping malls, buses and popular restaurants have also been targets. The embassy reminds US citizens of the importance of taking preventative measures to ensure their safety and security while traveling and residing in the Philippines," the advisory read.
