The Guardian posts an excellent summary of the latest developments:

• Two explosions have rocked Tripoli this morning. One appeared to be a tanker on the bridge near the Rixos hotel and the other was towards the coast. A witness suggested on Twitter that the former was the result of a traffic accident but it Tumblr_lhegmlaVUl1qc2aido1_500 will heighten nervousness in the capital, one of Muammar Gaddafi's few remaining strongholds.

• Forces loyal to Gaddafi have retaken at least two towns near the capital, according to the Associated Press. One of those apparently retaken was the strategic mountain town of Gharyan, the largest in the Nafusa Mountains.

A quieter day on the streets in Tunisia, but a tumultuous one inside the Government. Three Ministers left, including two former opposition leaders whose participation was considered a vital sign of consensus over the transition to elections and a new system.
