In Homs, already so devastated, the government bombardment is unrelenting.

Mosques have become morgues , places of worshipnow housing the dead.

"Haven't you gotten tired of killing us," this distraught woman asks of Syrian President Bashar al-Assad?"

Aren't you full enough from our blood?

In what religion is this permissible?

What did this child do to you?"

Everyone has become a target inrebel-held areas.

The victims are getting younger.

And medics struggle to revive children with mortal wounds.

Rebel fighters have warned an onslaught was coming since they lost Qusayr, a strategically important town between the Homs and Syria's border with Lebanon.

Now, the military has momentum.

And Bashar al-Assad's forces are aiming to vanquish the rebellion in the heart of the Syrian uprising.

Activists say this is the worst violence they've yet experienced in two years of conflict , that Homs is hit harder every day.

The opposition Syria National Coalition is urging the international community to interveneimmediately.

The UN agency for human rights warns it is extremely concerned about the human rights and humanitarian impact of the assault in Homs.

It says between 2,500 and 4,000 people may be trapped there, many in need of medicine and food.

As residents look for more bodies, fears are only growing with help for noncombatants nowhere in sight.
