A UN team probing the assassination of Lebanon's former prime minister will seek another year to continue its work, and is not expected to make any new revelations about who was responsible in a report due later Saturday, UN diplomats said. The report from Belgian prosecutor Serge Brammertz's investigators will stress that much work remains to get to the bottom of the Feb. 14, 2005 bombing in Beirut that killed Rafik Hariri and 22 others, the diplomats said on Friday. It will note that Syria has cooperated in some respects, they said. The diplomats spoke on condition of anonymity because Brammertz's report has not been made public. It is expected to be delivered to UN Secretary-General Kofi Annan and the Security Council on Saturday. The diplomats said that Brammertz's latest report will view Syria's more recent cooperation more favorably, mostly because Syrian President Bashar Assad finally agreed to be interviewed by Brammertz after twice declining. That happened on April 25.
