North Korea's firing of artillery rounds into South Korea 'dangerous and provocative': White House

North Korea's recent actions, which include firing of artillery rounds into South Korean waters, are "dangerous and provocative" and the country's threats and provocations only isolate it further, a White House
official said on Monday.

"We remain steadfast in our commitment (to) the defense of our allies and remain in close coordination with both the Republic of Korea and Japan," White House National Security Council spokesman Jonathan Lalley said.
