MANILA, Philippines -- The Philippine government is ready with a contingency plan in case the row between North Korea and South Korea escalates towards a nuclear battle.

In a text message, Presidential Communications Operations Office Secretary Herminio "Sonny" Coloma Jr. said the National Disaster Risk Reduction & Management Council (NDRRMC) has a “continuing contingency plan to respond to external threats, including previous missiles launched from the two Koreas.”

In the meantime, the Philippines remains vigilant and will adhere to “diplomatic modes of conflict resolution,” he said.

The Philippine Embassy in Korea is also ready to coordinate with Filipino communities there in case the tension escalates.

“The President has directed the [Department of Foreign Affairs] to ensure that the Philippine embassy in Korea coordinate with the Filipino community there. For this reason, the Embassy is coordinating with Filipino community leaders on steps to be taken pertinent to the situation in the Korean Peninsula,” presidential spokesperson Edwin Lacierda added.

North Korea earlier announced it has entered a "state of war" with South Korea, warning that any provocation from outsiders would end in a nuclear fallout.
