What has Assad done to the residents of Baba Amr?

Valerie Amos, the UN under secretary general for humanitarian affairs, was finally authorized by the Syrian government to enter Baba Amr on Thursday.
This Homs neighborhood was shelled continuously by the Assad regime's armed forces for four weeks.
At least 950 craters are visible on open lands, such as roads and farmland, from the impact of indirect fire weapons. The number of craters indicates the frequency of attacks and how many artillery and mortar shells have fallen. There are 640 buildings in the neighborhood with visible damage. However, the damage to buildings is likely to be significantly underestimated from viewing the satellite image because views from satellite images do not show hits to the sides of buildings made by explosive weapons, Human Rights Watch said after having examined a satellite photo of Baba Amr taken on February 25, five days before the shelling stopped.
I was horrified by the destruction I saw. Almost all the buildings had been destroyed and there were hardly any people there. I am extremely concerned as to the whereabouts of the people who have been displaced, Ms. Amos wrote in a statement released on Friday.
The authorities have not provided any information concerning the fate of Baba Amr’s residents.
Did they flee; were they victims of mass arrests, or killed? We do not know...
Ms. Amos has asked for unrestricted access to all areas subjected to violence in Syria, but has yet to receive an official response from the Assad government…
According to the BBC, activist groups continue to report the summary execution of men in Baba Amr, the butchering of entire families, and the systematic mass rape of women.
Outside of Homs, scores of civilians were killed in what was described as a new massacre by opposition activists.  Forty-four of them reportedly belonged to just two families…
A similar massacre was reported near Idlib, when troops opened fire, killing some twenty civilians.
The regime blames the violence on what it calls armed terrorist gangs.
Tanks also targeted the Homs neighborhood of Karam al-Zeitoun.
Thirty tanks entered my neighborhood at seven this morning and they are using their cannons to fire on houses, Karam Abu Rabea, a resident of the neighborhood, told Aljazeera.
Although the uprising began one year, the regime is remaining steadfast, according to senior US intelligence officials quoted in the WP, and Assad is very much in charge.
The Alawite establishment that governs the country has remained unified and determined not to relinquish power.
With so much blood having been shed by its security apparatus, it has no other option but to fight to the finish.
Were Assad to cede power, then he and his inner circle would no doubt face war crimes charges…
Hence, the uprising launched by the pro-democracy movement will be a long and bloody one, no doubt.
That leadership is going to fight very hard. The odds are against them, but they are going to fight very hard, one US intelligence official told the WP.
Meanwhile, the special envoy of the UN and the Arab League, Kofi Annan, will be in Damascus today to try and find a political solution to the Syrian crisis.
We will be urging the government and a broad spectrum of Syrian opposition to come together to work with us to find a solution that will respect the aspirations of the Syrian people, Annan said yesterday in Cairo.
The Syrian opposition did not look favorably upon this initiative, however.
It feels like we are watching the same movie being repeated over and over again.
My fear is, like other international envoys before him, the aim is to waste a month or two of pointless mediation efforts, Burhan Ghalioun, head of the Syrian National Council, told AP yesterday.
Indeed, while Mr. Annan negotiates with Assad, the latter’s forces will continue killing men, women and children…
