Gaza update: Israeli forces enter Gaza's second largest city Khan Younis

Israel says its troops have entered southern Gaza's largest city Khan Younis . The Israel Defense Forces says its troops have reached the heart of Khan Younis and have the city surrounded, following what it describes as the most intense day of fighting so far. Israel says it has expanded its offensive into southern Gaza as part of its operation to eliminate Hamas, which is classified as a terrorist group by many countries. Speaking on Tuesday, Israel's Prime Minister, Benjamin Netanyahu, said his country's forces have so far killed around half of Hamas' commanders in the Gaza Strip.
Meanwhile, the World Health Organisation says the security situation in Gaza is getting worse by the hour. As Israeli troops storm Khan Younis in the south in pursuit of Hamas, there's little hope for the hundreds of thousands of Palestinian civilians caught in the crossfire.
