The death toll in Gaza rises to 428 on the 6th consecutive day of Israeli airstikes; we feature a frontline report of an air attack on a densely-populated refugee camp and a children's park, and we'll hear about the extra-judicial killing of a senior Hamas leader, along with his wife, three children and ten family members whose home was blown to pieces by a US-made missile; we also report on continuing attacks on medical workers and grave shortages of medical supplies in key hospitals around Gaza.
