As world leaders including Hillary Clinton, Kofi Annan and Russia's Sergei Lavrov prepare for emergency talks on Syria, embattled President Bashar al-Assad said on Thursday that he will not be influenced by other nations, adding that it is the responsibility of the Syrian government ... to annihilate terrorists in any corner of the country.

Foreign pressure will not have an influence on our stance, Assad told Iranian state television in a rare interview. We have been under pressure for a long time, and it did not have an effect in the past, and it will not have any influence in the future.

Meanwhile, activists said that up to 190 people were killed in the besieged city of Douma on Thursday in one of the bloodiest days of the 16 month-old crisis. Witnesses, speaking to Reuters, called it another massacre of the massacres by Assad and his secret police.
