BEIRUT (AP) — President Bashar Assad's forces pressed on with a military offensive in eastern Damascus on Thursday, bombing rebel-held suburbs where the opposition said a chemical weapons attack the day before killed over 100 people.

The government has denied allegations it used chemical weapons in artillery barrages on the area known as eastern Ghouta on Wednesday as "absolutely baseless." The United States, Britain and France have demanded that a team of U.N. experts already in Syria be granted immediate access to investigate the site.
