[Updated at 11:38 a.m. ET] An update on the casualties: Two American service members and two Afghan army personnel were killed in Monday's attack in eastern Afghanistan by a gunman wearing an Afghan National Security Forces uniform, ISAF and Afghan officials said.
At least 10 Americans were wounded as well, a U.S. military official told CNN.
[Posted at 7:37 a.m. ET] Several NATO and Afghan service members were killed Monday when an assailant wearing an Afghan service uniform opened fire on the group, NATO said.
The attack happened late Monday morning in eastern Afghanistan, said Maj. Adam Wojack, a spokesman for NATO's International Security Assistance Force.
The incident appeared to be the latest so-called "green-on-blue" attack, or strike against coalition members by people dressed in police or army uniforms. Assailants conducting similar subterfuge killed dozens of coalition troops in 2012.
[Updated at 7:39 a.m.] North Korea has taken a step it's warned about for a few days: It declared invalid the armistice agreement that ended the Korean War in 1953.
That news, from the official newspaper of the country's ruling Workers' Party, comes four days after the U.N. Security Council passed tougher sanctions against North Korea in response to its February 12 nuclear test.
It remains to be seen whether the invalidation means that either North Korea or South Korea can resume hostilities. However, the North has nullified the agreement on several occasions in the past.
[Posted at 3:57 a.m.] Joint military exercises between South Korea and the United States began Monday, the South Korean defense ministry said.
The latest military drills involving the two allies are called Key Resolve and follow the Foal Eagle joint exercises that began March 1, which are scheduled to last two months.
North Korea has called the annual training exercises "an open declaration of a war," but South Korea says it notified Pyongyang that the drills "are defensive in nature."FULL STORY

Preparations, both spiritual and practical, neared completion at the Vatican on Monday, where Roman Catholic cardinals will gather to begin the process of selecting the next pope.
The conclave - the secret papal election - begins Tuesday in the Sistine Chapel, which has been closed to the public while Vatican staff readied the ornately decorated vestry for deliberations.
The first public signs of preparations appeared over the weekend as workmen scaled the roof of the chapel on Saturday to install the chimney which will release the black or white smoke that signifies whether a new pope has been elected.FULL STORY
Ten years after the fall of Saddam Hussein, Iraq remains "enmeshed in a grim cycle of human rights abuses," Amnesty International said in a report Monday.
"Many Iraqis today enjoy greater freedoms than they did under his Ba'athist regime, but the fundamental human rights gains that should have been achieved during the past decade have signally failed to materialize," said Hassiba Hadj Sahraoui, Middle East and North Africa deputy director at Amnesty International.
The report said government forces commit torture with impunity, targeting particularly those arrested on suspicion of carrying out terrorism acts.FULL STORY
Afghan President Hamid Karzai's contention that the United States was colluding with the Taliban is "categorically false," the commander for the NATO-led forces in the country said Monday.
"We have fought too hard over the past 12 years. We have shed too much blood over the past 12 years. We have done too much to help the Afghan Security Forces grow over the last 12 years to ever think that violence or instability would be to our advantage," said Marine Gen. Joseph Dunford, the commander of the International Security Assistance Force.FULL STORY
