After pummeling north Gaza, Israel has expanded its attack to the south since a temporary truce collapsed on Dec 1, Reuters reports.

Israeli tank shelling on Tuesday was focused on the centre of Khan Younis, southern Gaza’s main city, residents said.

After nightfall, Israeli air strikes on Khan Younis killed 11 Palestinians, including two children, health officials said.

In the south Gaza town of Rafah, which borders Egypt and where the Israeli army this month told civilians they would be safe, Gazans said the shelling was some of the heaviest in days. Health officials said 22 people including children were killed there.

Israel’s military said that over the past day, it hit several posts that were used to fire rockets at its territory, raided a Hamas compound where it claimed it found some 250 rockets among other weapons and struck a weapons production factory.
