The Islamic Resistance Movement (Hamas) and its rival Fatah on Wednesday decided to set up a fact-finding committee to investigate recent armed clashes between the two groups.
The decision was made after senior officials of the two groups met in Gaza under Egypt's sponsorship in an effort to end tension.
"The meeting focused on violations on the ground and how to prevent any future bloodshed," Hamas legislator Khalil al-Hayya told reporters.
Al-Hayya said that a referendum, proposed by President Mahmoud Abbas, was not discussed in the meeting.
For his part, Majed Abu Shamalla, a Fatah legislator, said that the two sides agreed to bring all the violators to justice.
The security situation in Gaza has been worsening as Hamas militants and Fatah members have clashed almost daily.
