Hamas spiritual leader Ahmed Yassin says Hamas will agree to a cease-fire in pre-1967 Israel, but only if certain conditions are met.
All Palestinian security prisoners must be released from Israeli jails, and all targeted killings of Palestinians must be halted.
Yassin says Hamas will only destroy its weapons after the creation of a Palestinian state.
Yassin was speaking to reporters in Gaza.
The Palestinian Authority is trying to persuade Hamas to agree to a cease-fire before U.S. President George W. Bush arrives in the Middle East next Tuesday.
