Guatemala is condemning the killing of a 13-year-old boy, allegedly by Belizean soldiers near the two countries' border.

President Jimmy Morales calls it a "cowardly and excessive attack" and says he has summoned his ambassador to Belize for consultations.

Guatemalan authorities say teenager Julio Rene Alvarado Ruano, his father and younger brother were attacked Wednesday as they planted crops near the Sarstun River in the northern department of Peten. The father and brother were wounded.

Belize's government said Thursday in a statement that its troops were investigating illegal logging when they detained a Guatemalan man just inside Belizean territory. It said the patrol came under fire around nightfall and responded in kind. It said that before leaving, the soldiers found the boy's body, which was taken to Belize City.
