Anchor: South Korean and U.S. military planners have been keeping an eye on two occasions: the anniversary of the founding of North Korea's ruling Workers' Party on October 10th, and the start of a Party congress in China on October 18th.  Military leaders say either occasion may offer North Korea an opportunity to engage in provocative behavior. 
Kim In-kyung has more.
 
Report: South Korean and U.S. forces maintained a bolstered defense posture in advance of  Tuesday's 72nd anniversary of the North Korean Worker's Party.

North Korea conducted a nuclear test a day before the anniversary in 2006, and held a massive military parade to mark it in 2015. 

On Saturday, North Korean leader Kim Jong-un promoted his younger sister Kim Yo-jong as part of a reshuffle of the party's powerful Central Committee. She was named as an alternate member of the Political Bureau of the Central Committee. 

Choe Ryong-hae, vice chairman of the Worker's Party and a close aide to Kim Jong-un, was appointed to the party's Central Military Commission.
 
In a speech at the meeting, Kim Jong-un reaffirmed his commitment to the simultaneous pursuit of nuclear weapons and economic development.
 
A Russian lawmaker who visited North Korea last week said Monday that the North is preparing to test an intercontinental ballistic missile which can reach the west coast of the United States.
 
Anton Morozov, a member of Russia’s lower house of parliament, told Kyodo News that Kim Yong-nam, president of the Presidium of the Supreme People's Assembly, discussed the type of missile the North plans to test and its maximum range.
