1845 GMT: Reuters posts the accounts of residents of the southern town of Daraa about the "inhumanity and criminality" of the military that occupied the town: "They occupied several mosques, including the Omari mosque and Sheikh Abdul Aziz (mosque), to ensure that even volunteers or imams cannot use minarets to ask for blood or urge medics to help the wounded....They stationed tanks even in public gardens and security patrols seem to have orders to shoot on the spot."
One activist said at least 18 people were killed by gunfire and tank shelling.
1515 GMT: Al Jazeera's Andrew Simmons reports from Misurata, where fighting has intensified:
"There seems to be a policy to attack civilians with mortar fire. A residential district here has recieved 16 hits, which took out two schools, and we don't know the exact casualty figures in these schools."
"What we do know is it may be quite high, considering that pro-Gaddafi forces are using what is termed as indirect fire - essentially lobbying shells and tank rounds to terrorise the population."
1448 GMT: Earlier, Scott Lucas had noted a video too graphic to post. He mistakenly linked to another important video of tanks deploying in Daraa. He has corrected the link.
1418 GMT: The Wall Street Journal is reporting that the Obama administration is preparing unilateral sanctions against Syria. According to the report, individuals closest to Bashar al-Assad will have their assets frozen and will face a travel ban, in a move similar to the recent sanctions against the head of the Basij force and the Tehran's head prosecutor in Iran.
These sanctions are unlikely to have a significant effect, but they are a clear sign that efforts to improve relations between Syria's government and the United States are being reversed.

Although regime forces have been pushed out of the centre of Misurata, Libya's third-largest city, the bombardment continues. The opposition reports that eight more people died on Sunday, making a total of 36 over two days. A World Food Programme ship with food, medical supplies and three fully working ambulances, reached Misurata's port on Sunday.
Late Sunday night, three explosions --- "the strongest...so far" according to correspondents --- hit Tripoli. Witnesses said a building inside Libyan leader Muammar Qaddafi's Bab al-Aziziyah compount was "flattened". A Libyan official taking journalists around the scene said 45 people were wounded, 15 seriously, and declared, "It was an attempt to assassinate Colonel Qaddafi." Three Libyan State TV went off the air for more than two hours after the attacks.
