After a two-year-long siege, the Syrian army moved into rebel-held areas of Homs on Tuesday shelling neighborhoods and raising fears of further bloodshed in Syria's third largest city.
Activists uploaded videos to YouTube that they claimed showed government warplanes bombing Homs during the offensive.
Homs — per-war population of 2 million — was once considered a capital of the revolution; the city's residents were an early force behind the anti-government protests that swept through Syria in the spring of 2011. Now, as the Syrian uprising has descended into civil war, the city is largely under government control, with the opposition retaining intermittent control of neighborhoods mainly in the Old City.
For much of the last two years, Assad's forces have been laying siege to rebel held areas of Homs, shelling neighborhoods and cutting off residents from access to food, medical care, and other basic services.
In February, as Homs' humanitarian situation worsened, the United Nations evacuated some 1,400 people trapped in the besieged neighborhoods; around 1,300 people, reportedly mostly fighters, stayed behind. In total, an estimated 150,000 people have been killed during Syria's three years of unrest and more than 9 million displaced, according to the British-based Syrian Observatory for Human Rights.
