Maliki said he had agreed with prosecutors on a date for them to visit Palestinian territories, but did not say when. "It depends on their ability to enter Palestinian territory without problems," he said. ICC prosecutors told Reuters earlier they aimed to make field trips to both the Palestinian and Israeli sides but had not yet sought formal Israeli permission.
Israel disputed the U.N. report on possible war crimes, saying its forces had upheld the "highest international standards." Gaza's dominant Hamas group ignored the accusations against it and called for prosecutions of Israeli leaders.
As a non-member of the ICC, Israel is under no obligation to cooperate, regardless of international pressure to do so. But a boycott of prosecutors could put Israel in awkward company.
Even Russia, a foe of the ICC, has met court prosecutors related to their inquiry into alleged crimes in Russia's 2008 war with Georgia and over the events leading up to the 2014 overthrow of Ukraine's pro-Russian president.
Israel has been an outspoken critic of the ICC, saying the Palestinian Authority is not a state and should never have been admitted as an ICC member.
Israel also argues that the ICC inquiry will make it harder to reach a peace settlement with the Palestinians. Talks on a Palestinian state in territory Israel captured in a 1967 war collapsed last year, and there is little prospect of reviving them.
