A North Korean soldier successfully defected to South Korea Monday with a gunshot wound, per Reuters. He defected by leaving his guard post and heading towards the Demilitarized Zone (DMZ) between the North and South, The Guardian reports.

Why it matters: This type of event can exacerbate current tension between the two nations. South Korea's military has upped its level of alertness following the event, but as of yet, there has been no official comment from North Korea.

What happened: According to South Korea's defense ministry, South Korean soldiers heard gunshots and then found the defector 50 meters south of the border village of Panmunjom. It wasn't immediately clear his reasoning for defecting or how serious his injuries were.

Rare event: These sorts of defections do not happen often because the soldiers selected to serve at the DMZ have usually demonstrated loyalty to the North Korean regime. One soldier from the North crossed the border through this same town in 1998. Two other soldiers have taken a similar course this year.

The Trump administration’s full-steam-ahead push to fully reopen schools this fall is on a collision course with the U.S.' skyrocketing coronavirus caseload and its decades-long neglect of public education.

Why it matters: Getting kids back to school is of paramount importance for children and families, especially low-income ones. But the administration isn’t doing much to make this safer or more feasible.

As the coronavirus poses risks and concerns for the youngest and oldest Americans, the generations in the middle are buckling under the increasing strain of having to take care of both.

Why it matters: People that make up the so-called sandwich generations are typically in their 30s, 40s and 50s, and in their prime working years. The increasing family and financial pressures on these workers means complications for employers, too.
