Islamic Hamas movement on Tuesday emphasized it will persist talks with its political rivals until reaching an agreement that restores unity to the Palestinians.

"We will chase down Fatah movement everywhere by dialogue until we draw it back to the Palestinian field," said Mushier al-Massri, a Hamas lawmaker based in the Hamas-controlled Gaza Strip.

As Hamas and President Mahmoud Abbas's Fatah are scheduled to resume talks in Cairo on April 26, al-Massri said his movement "will seek a complete formation of a government."

If the dialogue fails, al-Massri added that Hamas "has a set of new ideas to reach the unity."

Al-Massri blames Fatah's sticking to "American and Israeli conditions" on the failure of the previous dialogue sessions that were held in recent weeks in Cairo.

Hamas and Fatah agreed on forming a transitional government and holding elections by 2010 but failed to agree on the political platform of the government and the electoral law.

Al-Massri said Hamas wants to end the political split between Gaza and the Fatah-ruled West Bank "through a national base that protects the resistance and faces the Israeli occupation and its conditions."

Fatah stresses that the government must be accepted to the international community by sticking to the peace deals.

Fatah emphasizes that the upcoming government must abide by international conditions and relevant peace deals but Hamas translates this as a recognition of Israel and thus rejects it.

Since Hamas routed pro-Abbas forces and seized Gaza in 2007, Abbas consolidated his rule in West Bank by forming a Western-backed government while Hamas tightened its grip on Gaza through an internationally-isolated administration.
