Hamas police exchanged fire Saturday with members of a clan allied with the rival Fatah movement, killing one man, medical officials said.
The death brought to five the number of people killed in recent days in the standoff between the ruling Hamas and the Hilles clan affiliated with Fatah, defeated during Hamas's takeover of Gaza in June.
The fighting was a sign of ongoing internal tensions, despite Hamas's assertions that it is in full control of Gaza.
The Hamas-Hilles dispute began earlier this week when Hamas security forces demanded that a member of the Hilles clan hand over a government-issued car. The clan refused and a gun battle erupted, killing three Hilles men and a Hamas police officer. A second Hamas policeman was critically wounded and remains on a respirator.
