Tanks in Syria have reportedly opened fire in the city of Homs, killing at least 10 people.
The Syrian Observatory for Human Rights, which is based in Britain, says the Baba Amr district came under heavy fire on Thursday.
Violence was also reported in other parts of the city.
The Arab League said on Thursday that Syria had agreed to a plan to withdraw all troops from urban areas and end all killing immediately.
Foreign journalists are unable to move around Syria freely and information is tightly controlled and hard to verify.
