Dani Miran, whose son Omri Miran is being held captive by Hamas, describes the message that Israel has resumed bombing Gaza as "horrific".
I am more worried than ever. I thought my son would be free within a week, he says to Israeli army radio.
Miran places a large part of the blame on the country's new army chief Eyal Zamir, who took up his post earlier in March.
This chief was chosen to fulfill the government's agenda – and its agenda is war.
Several former hostages express dismay. British-Israeli Emily Damari writes on Instagram that she is speechless and heartbroken after the news that the ceasefire is over.
"Acute" protest
The group Hostages and Missing Families Forum called for an "acute" protest outside Israel's parliament, the Knesset, in Jerusalem in the morning.
"The Israeli government has chosen to sacrifice the 59 hostages. The families are now taking to Jerusalem and calling on Israel's population to join them", they write in a statement according to Haaretz.
Israel's Defense Minister Israel Katz claims that the renewed attacks on Gaza aim to free all hostages. It is a "complete misconception", according to the relatives. Prime Minister Benjamin Netanyahu could have chosen to end the war to bring the hostages home, they say.
Netanyahu is working once again for the death of all hostages – including my son's – to preserve his leadership, says Yehuda Cohen, whose son is a hostage held by Hamas, to Israeli Ynet.
59 hostages remaining
Einav Zangauker, whose son Matan was kidnapped to Gaza on October 7, 2023, calls for protests.
"I'm going to Nir Oz (in southern Israel) to physically stop a renewed war", she writes on Facebook and accuses Netanyahu of putting his political survival ahead of the hostages' lives.
"This war will bury our families if it's not stopped", she continues.
In total, 59 hostages are still being held by Hamas and other extremist groups in Gaza. More than 20 of them are believed to be alive.
