Residents of Mexico's beachside city of Acapulco were reeling Friday after a hurricane left at least five people dead and neighborhoods underwater in a region still recovering from a devastating storm last October.

Resort city Acapulco and surrounding towns face flooding and landslides and concerns about food supplies after John strengthened into a Category 1 hurricane.

In Guerrero, the worst-hit state and one of Mexico's poorest, 18 people were killed, according to local media, many due to mudslides that crushed houses. To the south, local media reported three deaths in Oaxaca, and a young boy died in a river to the north in Michoacan state.
