Palestinian President Mahmoud Abbas denied accusations by Hamas that his Fatah movement was behind a deadly bomb attack that killed five Hamas members and a girl in Gaza two days ago.
Abbas renewed calls for dialogue with Hamas and voiced support for an independent committee of Palestinian figures and human rights activists to investigate the explosion.
The blast destroyed a Hamas car, killing the fighters and a girl and wounding 20 passers-by.
Speaking in Cairo after meeting Egyptian President Hosni Mubarak, Abbas said: "We would accept any decision that would result from this investigation committee because we do not accept the ugly actions that took place in Gaza."
"What happened was very regretful and painful to our people and we do not accept it at all," Abbas told reporters in remarks carried by Egyptian State News Agency MENA.
Abbas said Egypt would call representatives of Palestinian factions "within days" for dialogue sessions in Cairo.
Hamas official Sami Abu Zuhri said Abbas's call for dialogue with Hamas was "not honest," saying investigations into Friday's killings showed some senior Fatah officials were involved.
"The bombing and killings in Gaza proved that Fatah was not interested in dialogue with Hamas, and all they aspired (to) was to cause anarchy and chaos," the Hamas spokesman said.
Abbas arrived in Cairo on Saturday to discuss with Mubarak the latest in the Palestinian-Israeli talks.
He said Palestinians should pursue talks with the Israelis despite obstacles such as settlements, continued Israeli army raids into the West Bank, checkpoints and the presence of Palestinian prisoners in Israeli jails.
"It is in the interest of our people that we should pursue the negotiations even if there was only a one percent hope it would succeed," Abbas said.
