The hits just keep coming.

BAGHDAD - Iraqi militants said on Thursday they would fight for "months and years" to free their country from U.S.-led occupation as their nemesis President Bush was inaugurated in Washington for a second term.

Hours before Bush was sworn, a group led by al Qaeda ally Abu Musab al-Zarqawi released an audio tape urging Islamist militants to prepare for a lengthy holy war.

The group, which has staged most of the deadliest suicide attacks in Iraq in the run-up to elections on Jan. 30, said it was crushing the morale of "tyrant" America.

Another Iraqi insurgent group, Ansar al-Sunna, said it had killed a Briton and a Swede although the authenticity of the group's claim, posted on the Internet, could not be verified.
