In a letter Friday to the Israeli military’s chief of staff, Lt. Gen. Eyal Zamir, mothers of soldiers called for an end to the further ground offensive into Lebanon.

The group, Parents of Combat Soldiers, includes 600 military parents. The letter said the military was receiving orders from politicians who are ready to “sacrifice” its children, and urged Zamir to focus on a political solution. “Four soldiers have already been killed in Lebanon, how many more will sacrifice their lives in vain?!” said the letter.
