Sept 26 - Following are the latest political and military developments in the Libyan crisis.

* Libyan provisional government forces backed by NATO warplanes raced into the eastern outskirts of Sirte on Monday and fought street battles with Muammar Gadhafi loyalists.  

* The United Nations has food and medical supplies on the outskirts of Gadhafi's bastion, Sirte, and cannot get in to distribute them, the U.N.'s top humanitarian official in Libya said on Monday.

* Libya's sovereign wealth fund, which is conducting a review of all investments made by the toppled Gadhafi regime, has uncovered potentially large losses in its $5 billion Africa portfolio, its acting chief executive said.

* Scottish prosecutors have asked Libya's interim rulers for help in tracking down information which could lead to others, even Gadhafi, being charged over the 1988 bombing of a U.S.-bound airliner over Lockerbie in Scotland. The request was rebuffed.

* NATO said it conducted 104 air sorties on Sunday, 42 of them strike sorties to identify and hit targets.

* It said key targets hit included:

-- One command and control node, two ammunition vehicle storage facility, one radar facility, one multiple rocket launcher, one military support vehicle, one artillery piece and one ammunition storage facility in the vicinity of Sirte.
