Angry protesters have confronted visiting Arab League monitors in Syria's restive city of Homs, demanding international protection.
The observers are verifying compliance with an Arab League plan to end the government's violent crackdown.
Tens of thousands protested in Homs as the monitors arrived. The Arab League said the first day was "very good".
Tanks reportedly withdrew before the monitors arrived but activists say some were simply deployed out of sight.
The UN says more than 5,000 people have been killed in protests against President Bashar al-Assad's rule since March.
