Earlier this week, Israel declared a state of war and launched an operation in the Gaza strip against Hamas and announced a complete blockade of food, water and electricity in the area. On Thursday, Israel told the population of northern Gaza - roughly 1.1 million people - to evacuate to southern Gaza within 24 hours. The UN, Amnesty international and multiple governments have urged Israel to revoke the order.
On Thursday, Syrian state media reported that Israeli airstrikes has simultaneously hit two airports in the country, causing flights in Damascus and Aleppo to be diverted.
