-- Two US warships carrying marines and equipment have entered the Suez Canal and are heading towards Libya, as the West flexes its military muscle.
-- The UN refugee agency has warned that the situation on the Libya-Tunisia border is reaching crisis point as desperate migrant workers flee for safety. More than 100,000 people have already left Libya to escape a vicious crackdown by Kadhafi loyalists which has left at least 1,000 dead, according to conservative UN estimates.
-- Western powers are arguing over imposing a proposed no-fly zone over Libya to support rebels fighting Kadhafi's regime.
-- Kadhafi opponents are beginning to organise the trappings of parallel government. Rebels in Benghazi said they had formed a military council in the eastern Libyan city, the hotbed of the uprising against Kadhafi's four-decade iron rule.
1030 GMT Several hundred pro-Kadhafi supporters -- some carrying Kalashnikov rifles -- are rallying near the site of a petrol tanker explosion near the compound of the Libyan leader in Tripoli, an AFP reporter says.
Flames shot up to four metres (12 feet) in the air after the tanker overturned and split open. The blast happened near a mosque and a hotel but there appeared to be no casualties, according to our correspondent on the ground.
1040 GMT Kadhafi's forces enter the rebel-held eastern town of Brega, sparking fierce clashes, witnesses and opposition sources say.
A resident of Brega -- 200 kilometres (125 miles) west of the main eastern city of Benghazi -- tells AFP by phone that Kadhafi's forces stormed the town with tanks and heavy artillery, and describes violent fighting at the port.
A doctor in Ajdabiya -- 40 kilometres from Brega -- tells AFP the attack began under cover of darkness:
"During the night Kadhafi's forces attacked the airport at Brega where they clashed with the rebels," said Aymane al-Moghrabi.
1100 GMT Kadhafi's forces have launched air strikes on the rebel-controlled town of Ajdabiya in the east of the country, witnesses tell AFP.
According to the BBC, pro-Kadhafi jets bombed an arms dump in city which it says is "in a high state of excitement".
1055 GMT The UNHCR makes a plea for hundreds of planes to end a gridlock at the Tunisia border with Libya, where it says "acres of people" are still waiting to cross in freezing conditions.
"My colleague on the ground say that acres of people, as far as you can see, are waiting to cross," UNHCR spokeswoman Sybella Wilkes tells AFP.
"There's a huge building and there are thousands behind," she adds.
"They are outdoors in the freezing cold, under the rain, many of them have spent three or four nights outside already.
"It's really chaotic."
Some 77,320 people have already crossed into Egypt, UNHRC Wilkes says, while a similar number have crossed into Tunisia.
"We're looking at over 150,000 people who have fled into the two countries," she estimates.
The UN refugees agency is particularly concerned about the situation on the Tunisian side of the border, where a huge transit camp has been set up. Up to 10,000 people spent the night in the tents, squeezed in like sardines to keep out of the rain and cold, the agency says.
