International mediators including the US have been working for months to get a deal that would see the release of the hostages still held by Hamas and an end to the war in Gaza.
Gallant said reaching a deal with Hamas was “a strategic opportunity that gives us a high chance to change the security situation on all fronts”.
He warned against regional escalation of the conflict and suggested that it would only benefit Hamas leader Yahya Sinwar.
Gallant called on the international community to pressure Hamas to agree to a ceasefire deal.
He said: “Israel should achieve an agreement that will bring about a pause for six weeks, and bring back hostages. We maintain the right to operate and achieve our goals — including the destruction of Hamas.
“The scenario of a full-scale, multi-front war benefits Sinwar. That’s what he dreamed of when he led a brutal attack against Israeli children, women and men.”
