Hundreds of people have been killed in a Gaza refugee camp. Here's what to know

 Some 300 people have been killed in the Jabalya refugee camp in northern Gaza since the beginning of the latest Israeli ground operation in the area nine days ago, the Gaza Government Media Office said Sunday.

The office said heavy fighting meant emergency workers had not yet been able to recover dozens of those who have been killed in the area, leaving decomposing bodies in the streets and buildings. Many civilians told CNN it was too dangerous to evacuate their homes.

Here’s what to know from elsewhere in the region:

In Lebanon: Three mosques in southern Lebanon were hit by Israeli fire, leaving them partly or fully destroyed, amid cross-border hostilities between Hezbollah and Israel. Videos posted on social media and geolocated by CNN showed a pile of rubble where the Kfar Tebnit mosque minaret once stood.

The Israeli military also expanded its evacuation warnings to residents of 21 more villages in southern Lebanon on Sunday, urging them to move further north into the country, while Israeli Prime Minister Benjamin Netanyahu warned the UN that UNIFIL peacekeeping forces in Lebanon are in “harm’s way,” calling on Secretary-General Antonio Guterres to get them out.

Separately, on Sunday morning, four Lebanese Red Cross volunteers were injured by a double Israeli airstrike on a house in Srebbine, southern Lebanon, the organization said.

Israel’s military operations: At least two Israeli soldiers were severely injured during combat operations in southern Lebanon, the Israel Defense Forces (IDF) said on Sunday. The military also said it captured a Hezbollah fighter while storming one of the group’s tunnels and hideouts in southern Lebanon.

Iran: Iran has “no red lines” in defending its interests, the country’s Foreign Minister Seyed Abbas Araghchi said Sunday.

“While we have made tremendous efforts in recent days to contain an all-out war in our region, I say it clearly that we have no red lines in defending our people and interests,” Araghchi said in a social media post, also criticizing US arms deliveries to Israel.
