Video of a sea barrier Israel is building to prevent attacks from Gaza, which is ruled by the Islamic militant group Hamas, has been published by Israeli Defence Minister Avigdor Lieberman.

His Twitter post came on Sunday as Israeli Prime Minister Benjamin Netanyahu reportedly convened his security cabinet to discuss an Egyptian brokered ceasefire between Israel and Hamas.

Lieberman wrote: "We are continuing intensive work to build land and sea obstacles around Gaza. Hamas is losing its capability to attack Israel every day."

As part of the negotiations, several exiled Hamas leaders are in Gaza for talks.

Israel and Hamas came close to serious conflict recently when months of border violence escalated.  

Hamas has led weekly border protests partially aimed at drawing attention to the Israeli-Egyptian blockade imposed after it took control of Gaza in 2007.
