"The success of Hamas in closing Israeli airspace is a great victory for the resistance, and is the crown of Israel's failure," Hamas spokesman Sami Abu Zuhri said in a statement.
A rocket fired from the embattled Palestinian territory hit near Tel Aviv's Ben Gurion airport on Tuesday, prompting US and European airlines to suspend all flights to and from the Jewish state.
The flight ban was still in place today, as Israel bombarded Gaza for a 16th straight day in an operation to stop rocket fire and destroy tunnels constructed by Hamas, the main power in the territory.
Israel's Iron Dome air defence system has intercepted 433 rockets.
