Palestinian health workers said Israeli strikes killed at least 23 people in the Gaza Strip overnight into Tuesday. The dead included three children and their parents, who were killed in a strike on their tent near the southern city of Khan Younis, according to Nasser Hospital, which has received a flood of dead and wounded since Israel resumed heavy bombardment of Gaza last week, shattering the ceasefire that had halted the 17-month war.
