Israeli strikes in Gaza have killed at least 30 Palestinians, marking one of the highest tolls since the October ceasefire. Hospitals in Gaza say several children are among the dead after strikes on an apartment building in Gaza City and a tent camp in Khan Younis on Saturday. An airstrike on a police station in Gaza City killed and wounded at least 14. The strikes came a day after Israel accused Hamas of new ceasefire violations. They also came a day before the Rafah crossing with Egypt is set to open, marking a significant step as the second phase of the U.S.-brokered ceasefire advances.
