Three dozen leaders at news organizations around the world have signed a letter expressing solidarity with journalists in Gaza, calling for their safety and freedom to report in the war zone.

An Israeli strike in Syria on Friday killed an Iranian Revolutionary Guard and two other people, reports said, in the third consecutive day of Israeli attacks on Syria.

Israel hit a car used by Hezbollah in Syria, close to the Lebanese border, also striking near Damascus Thursday, a war monitor said, hours after similar attacks near the Syrian capital.

Israeli forces in war-torn Gaza opened fire on a crowd of Palestinians at an aid distribution point Thursday, killing at least 104 people and wounding over 700 according to Palestinian health officials.

Israel has carried out strikes near Damascus, Syria's defense ministry said, the latest reported attack amid soaring regional tensions since the start of the Israel-Hamas war in Gaza.
