The ICRC said the Syrian Red Crescent had evacuated a total of 27 people from Baba Amro on Friday.
Four Western journalists, two of whom were wounded in an attack that killed two other foreign journalists on Wednesday have yet to be extracted from the shattered neighborhood.
Activists in Homs, a city of over 800,000 people located at the junction of highways leading from Damascus to Aleppo and the coast to the interior, described Friday's Friends of Syria meeting in Tunisia as a failure that had brought them no relief.
"I don't really care about the Tunis conference. All I care about is getting help for my family in the besieged areas," said Waleed Fares, contacted from Beirut. "The political calculations are not the same as the calculations for us revolutionaries."
A video uploaded by activists in Homs' Khalidiya district showed crowds at a funeral, shouting "We swear to God we will not be silent about our martyrs." In the background, clouds of smoke were rising from buildings that activists said had been hit by shell fire.
Civilians are enduring desperate conditions in Baba Amro.
"We have hundreds of wounded people crammed into houses," the activist Husseini said. "People are dying from lack of blood because we just don't have the capability of treating everyone."
The Tunis conference of Western, Arab and other countries was intended to ratchet up diplomatic pressure on Assad to end an almost year-long crackdown on opponents of his 11-year rule in which thousands of Syrians have been killed.
