Israeli military launches new ground offensive in Gaza, kills 20

Amid the airstrikes, the Israeli military on Wednesday said that its forces have resumed ground operations in the central and southern Gaza Strip, reported Reuters.

According to local health workers, atleast 20 Palestinians have been killed on the second day of airstrikes.

Earlier on Tuesday, over 400 Palestinians were killed in airstrikes in one of the deadliest episodes since the beginning of the conflict, shattering a ceasefire that has largely held since January.

Meanwhile, the Israeli military stated that its operations have extended Israel's control over the Netzarim Corridor, which bisects Gaza. They added that the operations were a "focused" manoeuvre aimed at creating a partial buffer zone between the north and the south of the enclave.

The United Nations said an Israeli airstrike had killed a foreign staffer and wounded five workers at the site of a U.N. headquarters in central Gaza City on Wednesday.

Denying this, Israel said their airstrikes had hit a Hamas site, where it had detected preparations for firing into Israeli territory.

Jorge Moreira da Silva, executive director of the UN office for Project Services, said, as quoted by Reuters, "Israel knew that this was a U.N. premises, that people were living, staying and working there, it is a compound. It is a very well-known place."

Israel, which has vowed to eradicate Hamas, said its latest onslaught was "just the beginning".
