Senior security sources have noted an increase over the past two weeks in attacks on Israel from Gaza, leading them to question Hamas’s motivation or ability to continue to enforce the truce that has been in effect since November 2012’s Operation Pillar of Defense.

Hamas’s ability to enforce the cease-fire may be in decline because of growing pressure from Egypt, which has sealed smuggling tunnels linking Gaza to Sinai, and because of the Egyptian military government’s general hostility toward Hamas due to the group’s affiliations with Egypt’s Muslim Brotherhood.

The closing of the tunnels has had a negative impact on Gaza’s economy. As such, the increase in attacks might be tied to Hamas’s lesser ability to govern Gaza and impose its will on other terror groups.
