If North Korea launches a missile attack on Guam, it would take about 14 minutes for the rockets to reach the US territory, the island’s Homeland Security spokeswoman said, according to a report.

Jenna Gaminde said residents of the Pacific island would be immediately notified.

“Our office will be notified from the military and will utilize all forms of mass communication to get the message out to the public,” Gaminde said​, including local media, village mayors and social networks, the Pacific Daily News reported.

“If you hear the sirens, tune into local media ​—​ radio, print, television —​ for further instructions,” Gaminde said.

North Korean military officials said they would present a plan to President Kim Jong Un in about a week on how ​they would carry out an attack on Guam, where about 7,000 US troops are stationed.

The initial plan calls for sending 12 rockets over Japan to crash in the waters about 30 miles from Guam, which is 2,100 miles east of the Korean peninsula.
