Human Rights Watch says Syrian security forces have "forcibly removed" 18 wounded people from a hospital in Homs during a raid on the city this week.
The rights group cited witnesses, including doctors, in a report it released on September 8.
The central city of Homs has been a flashpoint of protests against President Bashar al-Assad's regime.
Activists say at least 20 people were killed during a raid on September 7.
The United Nations estimates that more than 2,200 people have been killed in the crackdown since protests against Assad's regime began in March.
