Israel has resumed its ground and aerial offensive in the Gaza Strip following relentless rocket fire by Hamas militants.

Ending the extension of the temporary ceasefire, which was due to stay in effect until tonight (27 July), the Israeli Defence Forces (IDF) said they are resuming their attack "due to flagrant violations of humanitarian remission by Hamas".

"Following Hamas's incessant rocket fire throughout the humanitarian window, which was agreed upon for the welfare of the civilian population in Gaza, the IDF will now resume its aerial, naval and ground activity in the Gaza Strip," the IDF said in a statement.

"The IDF again urges the Palestinian population not to approach combat areas."

At least a dozen rockets have been fired by Hamas at Israel overnight, said the IDF.

So far, at least 1,000 Palestinians and 46 Israeli soldiers have been killed in the latest conflict.

Israeli health minister Yael German told Channel Two news that the Palestinians are refusing any Israeli humanitarian aid sent through the Red Cross as well.

"Even when we send the aid through the Red Cross, there is no one on the other side willing to accept medicine. They don't want the world to see us doing anything humanitarian."
