Islamabad, Pakistan (CNN) -- A water dispute in Pakistan's tribal region has led to over two weeks of fighting and dozens of deaths, government officials said Sunday.

The conflict is centered in Kurram Agency, one of the seven districts of Pakistan's restive tribal region which borders Afghanistan.

Sixteen days ago, the Mangal tribe stopped water irrigation on lands used by the Tori tribe, according to Mumtaz Zareen, a senior government official in Kurram Agency.

Zareen told CNN that 116 people have been killed, including 13 on Sunday alone.

Another 165 people have been wounded over the course of the dispute.
