MANAGUA, Nicaragua (AP) — Nicaragua’s president is placing his government on the highest alert level as aftershocks rattle the country following a magnitude-6.1 earthquake.

The government Friday raised the number of injured people from 23 to 200. It also said that a 23-year-old woman had died of an apparent heart attack after the quake.

President Daniel Ortega said that he was raising the country’s alert level to red, meaning everyone in situations at risk of harm from aftershocks must be evacuated.

In the capital, Managua, 155 people were evacuated due to risk of landslides, and schools were closed in the capital and in the northwestern city of Leon.

The government said roughly 800 homes were damaged in the town of Nagarote and surrounding areas, about 30 miles northwest of the capital.
