Israel and Palestinian militants are at war after stunning and deadly surprise attacks by Hamas on Saturday that coincided with a major Jewish holiday and the 50th anniversary of the start of the 1973 Yom Kippur war. It was one of the most significant attacks on Israel in decades, with militants infiltrating 22 towns and army bases. More than 600 Israelis have been killed since Hamas militants began their assault, volunteer group ZAKA told Israeli media.

Israel responded by rushing troops to the border area of Palestine's Gaza City and launching airstrikes across the blockaded territory. Palestinian officials say more than 300 Gazans have been killed.

Josh Gad says 'we are all losers' in Israel-Palestinian conflict

Josh Gad expressed sadness for lives lost in Israel on Threads Saturday. "I have no words. I am praying for my many family members in Israel. What a cowardly act," he wrote. "What we are witnessing in real time right now is unprecedented since the Yom Kippur war. My heart breaks for the families of those who have lost loved ones, and for the hostages who have been taken. What a horrific day."

On Sunday, Gad said that he was "personally attacked, shamed, unfollowed and threatened" for expressing sympathy for Israeli citizens killed in a surprise attack orchestrated by the Hamas.

"Instead of compassion & humanity, people are treating this as if it’s a FOOTBALL match with two teams when the points scored are dead human bodies. Waving flags around as if they are team jerseys," he continued. "Somewhere in a basement right now, tied up and terrified are little CHILDREN who have never done anything to hurt a Palestinian. Somewhere on the streets of Gaza are innocent people who are being shelled, because terrorists decided it was best to destroy any opportunity for peace."

Gad, who said he has also "been critical of the Israeli Government and it’s pattern of occupation and their attacks on innocent Gazans," added that he was sadden that there isn't "communal despair" around the current situation in Israel.

"There are no winners here. We are all losers. Most importantly, every Israeli and Palestinian is now on the losing end," he concluded. "I am truly at a loss. I guess I’m the naive one."

Sara Foster, who starred as Jen Clark on "90210," took to her Instagram story Sunday to criticize Palestinian influencers who have stayed silent on the recent violence committed by Hamas in Israel.

Foster, daughter of music producer David Foster, added that "you can still be a proud Palestinian who holds Hamas accountable for this."

What is the Israeli-Palestinian conflict?

One of the world's most enduring and intractable conflicts connects to a century of competing claims to land, borders and rights in a region of deep historical and religious significance.

The United Nations in 1947 tried to divide the-then British Mandate of Palestine into separate Arab and Jewish states. A year later, when the state of Israel was created, the first Arab-Israeli War broke out. Ever since Israel's victory and following several other wars, Palestinians have gradually been displaced from territory that they also see as their rightful homeland.
