Do abilities and spells by enemy players affect the Capital City?

Abilities and Spells performed by enemy players cannot affect the Capital City from OUTSIDE, but during a Battle INSIDE the Capital City Region, abilities can take effect. For example, an enemy player cannot cast "Earthquake" and cause another player to lose Units from their Capital City. But, if they were in a Battle with the Capital City, they could cast "Fireball," causing a loss of Units there.
