CAIRO - Hamas has reportedly agreed to an 18-month Gaza truce with Israel.

Egypt's official Middle East News Agency quotes Hamas deputy leader Moussa Abu Marzouk as saying the Egyptian government will announce the truce in two days after consulting with other Palestinian factions.

Marzouk says the deal calls for Israel to reopen six border crossings into the Gaza Strip.

In Jerusalem, Prime Minister Ehud Olmert's office said the Israeli government had no comment on the report.

Earlier in the day, Egyptian and Hamas officials reported progress in truce talks, which included Hamas' strongman from Gaza, Mahmoud Zahar, and Egypt's top mediator, intelligence chief Omar Suleiman.

Egyptian diplomats have been working as go-betweens to solidify a ceasefire that ended Israel's devastating 22-day offensive in Gaza last month. Hamas and Israel refuse to negotiate directly.
