Gaza separated by destroyed bridge
The BBC's Lyse Doucet reports from the Gaza Strip where she finds the main coastal road connecting north and central Gaza to the south has been destroyed by Israeli forces.
Overnight, Israel's military, the Israel Defense Forces (IDF), said it had attacked more than 100 sites in Gaza "of which approximately 50 were underground rocket launchers".
The IDF said 29 rockets had been launched into Israel by militants in Gaza, of which 12 were intercepted by its Iron Dome missile defence system.
The latest violence will further complicate ceasefire discussions taking place in the region.
