HONOLULU -- The head of the U.S. Pacific Command said there is no reason for people in Hawaii to be concerned with North Korea's missile launches.

The reassurance came after reports that North Korea fired at least five mid range missiles Friday.

"There's no real reason to be alarmed. We're well prepared to defend American citizens and American property so there's no reason to be alarmed about the demonstration of firepower North Korea is suing. But there's reason for concern of this blatant disregard of normally accepted standards of behavior," said Admiral Anthony Keating, Commander U.S. Pacific Command.

Keating said North Korea's missile launches are in clear violation of the United Nation's Security Council's resolutions.

"There are some people who feel by flexing your muscle you can be recognized but in this world it takes more than flexing muscle; and I hope that Kim Jon Il realizes that because if he fires long-range then he is asking for trouble. We're not initiating it," said Sen. Daniel Inouye, D-Hawaii.

Both Keating and Inouye said the United States has stepped up missile defense systems around the islands.

The Sea Based X Band radar has been sent out. An integral part of the missile defense system. It is able to detect and track incoming missiles.

North Korea has tried to launch missiles in the past around July 4.

North Korea said it is military exercises, but most see it as a way to defy the United States on Independence Day.
