(AP) — Fire officials in a Mississippi city say three recent fires in the same neighborhood were intentionally set.

Vicksburg Fire Chief Craig Danczyk tells WLBT a vacant apartment building went up in flames on Saturday. The second fire occurred at a home a day later and the third fire at another home on Monday.

Both homes were also vacant. Danczyk says the six-unit apartment building was a total loss.

Officials are investigating.
