Around 500 Arab leaders in the Kirkuk area met yesterday in Hawija (50 km west of Kirkuk city), including leaders of the Abeed, Jabbur, and AlbouHamdan tribes, and heads of local awakening councils. Their spokesperson, Hussein Ali al-Jabburi said the Arab tribes are "in a state of readiness" (in the event the Kurdish parties persist in their threat of annexation), adding that their tribal relationships "extend to all of the cities of Iraq".
Translation: it appears that the Kurds are ready to fight for their autonomy from Iraq.
This is also one of the most oil-rich areas of Iraq.
This could get very volatile, very quickly.
