Israeli opposition leader Yair Lapid has called for a strike to shut down the country’s economy in order to pressure the government to reach a deal to release the remaining hostages in the Gaza Strip, Reuters reports.

Lapid, a former prime minister, called on every Israeli “whose heart was broken this morning” to join a major protest in Tel Aviv later in the day. He also called on Israel’s main labour union, businesses and municipalities to go on strike.

His remarks came after Israel recovered the bodies of six more hostages from captivity in Gaza.
