Al-Qaida in Islamic North Africa has posted a new message saying it won't be held responsible for the fate of an Austrian couple it kidnapped two months ago, a US group that monitors terror Internet traffic said Monday. The Washington-based SITE Intelligence Group said the al-Qaida affiliate claimed it was "absolving" itself of responsibility for what happens to the two Austrians and sets new demands that include the release of two Muslim prisoners in Austria. Monday's posting came just hours after an earlier set deadline for conditions to be met for the Austrians' release expired. SITE said al-Qaida did not give any indication on the condition or whereabouts of the two hostages. Wolfgang Ebner and Andrea Kloiber went missing while on vacation in Tunisia in February.
