ARLINGTON, UNITED STATES (AFP)

The first early voters cast their ballots Friday for November's US presidential election, as Democratic candidate Kamala Harris headed for a campaign event focused on the hot-button issue of abortion.

Three US states, Virginia, Minnesota, and South Dakota, were starting early voting, a practice.

Dozens of people waited at an early voting polling station in the centre of Arlington, Virginia, just outside the capital, Washington, AFP journalists saw.

A number had "Harris-Walz" shirts, and some "Trump-Vance" signs were in front of the building.
