The sun sets over the smoking Nahr al-Bared refugee camp in northern Lebanon 04 June 2007. Lebanese troops unleashed artillery and tank barrages at defiant al Qaeda-inspired militants dug-in at the Nahr al-Bared camp today in an attempt to crush the gunmen in a 16-day standoff, whilst deadly firefights erupted in a Palestinian camp in southern Lebanon opening up a new front for the Lebanese army.
