Hamas has released footage showing long-range missiles being fired and members of its naval commando unit firing weapons.
The group claim the rockets shown in the footage have a range of over 75 kilometres and could reach Israeli cities of Jerusalem and Tel Aviv.
A commando unit is also shown swimming underwater with their weapons.
The release comes as eight members of the same family were killed in Gaza during Israeli air strikes on Thursday, as Hamas fighters continued to fire rockets towards Israel.
It's been an emotionally exhausting day in Israel and Gaza as hopes for peace were raised then dashed then raised then dashed again.
In the court of international opinion, this is how Israel wins a battle and still manages to lose the war.
Until the Israelis and the Palestinians find a way of resolving the underlining conflict this will not be more than a pause.
