BBC analysts believe Hamas’s isolation after losing the support of former allies Syria and Iran and the Egyptian authorities crack down on smuggling tunnels has brought about attacking Israel as a way to obtain concessions in any eventual ceasefire. Meanwhile Qatar and Turkey, both supporters of Hamas, are participating in ceasefire negotiations. Israel does not trust them. Israel says even if it adopts a ceasefire it will continue searching out and destroying recent tunnels Hamas has built to bypass Israel's border defences (Security wall and Iron Dome) which up to now have mostly succeeded in preventing attacks within Israel proper. The current modern tunnel system is the first time that Israeli forces have faced a weapon against which they have no previous experience. Hamas has learned from Hezbollah how to improve its use of tunnels. Tunnels are now sophisticated, with water, sewage, and lighting allowing for month-long stays. See
