The Hamas official said in the wake of a rocket attack on southern Israel that Gaza factions are committed to honoring the peace truce with Israel, The Jerusalem Post reported.
"I have met with armed factions over the past two days and they stated their position clearly: they are committed to calm as long as (Israel) abides by it," Haniyeh said.
The Post said the Popular Resistance Committees armed wing has accepted responsibility for the rocket attack, which caused no injuries in the stricken industrial zone.
The Hamas leader also took time Friday to deny the existence of any tension between his militant group and Egypt in relation to collapse of Hamas-Fatah talks being mediated by Egypt.
"In day-to-day relations there may be differences, this is true, but it does not mean that there is a strategic tension with our brothers in Egypt," Haniyeh said.
