A fragile ceasefire in Gaza is on the verge of collapse after Israel launched fresh airstrikes, closing crossings and leaving at least 51 Palestinians dead.
The escalation came after Israel accused Hamas of killing two Israeli occupation troops and wounding three others in Rafah on Sunday morning, which Hamas denies.
Israel said the escalation followed a "blatant violation of the ceasefire agreement" by Hamas.
Mediation efforts are scrambling to preserve the fragile truce.
