Hamas denied firing the mortar, and no armed faction took claim for the incident.
To avoid Israeli retaliation, Hamas claims to have arrested the culprits.
Hamas has arrested those responsible for firing a mortar toward Israel on Tuesday evening, Israeli security sources said late Tuesday.
Ynet quoted the sources saying that after the mortar was fired, Hamas relayed a message to Israel saying it would arrest the perpetrators, which it did later on Tuesday.
According to the sources, Israel told Hamas — which denied that it had fired the projectile — that if it didn’t take action against the forces who violated the ceasefire between Israel and the Gaza Strip, Israel would have to intervene.
I think (and pray) the ceasefire will hold.
