Israel pummeled Gaza City with more than 15 strikes Thursday, killing more than 40 people and injuring 120 others, the besieged enclave’s civil defense agency said, calling the tempo and number of strikes high compared with recent days.

The Israeli military kept up the pressure on northern Gaza on Wednesday, striking in a suburb of Gaza City, medics said, and told residents in a central part of the enclave to evacuate from an area where militants were firing rockets.

Israeli airstrikes have killed at least 26 people across Gaza as they struck Hamas security officers and an Israeli-declared humanitarian zone
