Seven Israeli soldiers have been killed in the past 24 hours, according to the Israeli military.
Four died as armed Hamas militants attempted to gain entry into Israel earlier on Monday.
Israel says the aim of its ground offensive is to eradicate a network of tunnels which are used by militants to gain access to the country.
