Israel has expanded its military operation into new neighborhoods in Gaza as the conflict with Hamas continues. The death toll from the Israeli offensive has reached 13,000, with thousands of them being children, according to the Hamas government. Israel is facing international pressure to justify the high number of civilian casualties. Qatari mediators are working on a deal to free some of the hostages held by Hamas, while Israel has accused the militant group of using a hospital to hide hostages and tunnels. The World Health Organization has called the hospital a 'death zone.'
