NBC's Richard Engel answers reader questions about Syria

American journalist Marie Colvin and French photographer Remi Ochlik were killed Wednesday in the Syrian city of Homs. NBC's Richard Engel reports.

The intense fighting in Syria between President Bashar Assad's forces and opposition rebels seems to be getting worse by the day. On Wednesday, a French photojournalist and a prominent American war correspondent working for a British newspaper were killed as Syrian forces intensely shelled the opposition stronghold of Homs. 

Weeks of withering attacks on the city of Homs have failed to drive out opposition factions that include rebel soldiers who fled Assad's forces. Hundreds have died in the siege - galvanizing international pressure on Assad, who appears intent on widening his military crackdowns despite the risk of pushing Syria into full-scale civil war.

NBC News' Chief Foreign Correspondent Richard Engel is on assignment along the Turkey-Syria border. He answered reader questions about the ongoing conflict in Syria earlier today.
