Israel says its bombing runs are just the beginning of an offensive that 'will only intensify.' Next comes the ground fight.

• Israeli warplanes continue to bombard Gaza as ground forces mass in the surrounding area.
• The country's defense chief said the air attacks are just the start and would be followed by action on the ground.
• Israel vowed to crush Hamas after the militant group launched its brutal attacks on Saturday.

Days after Israel officially declared war on Hamas following deadly attacks and atrocities, the country's continuous bombardment of the Gaza Strip has not let up. And as forces continue to mass near the border, Israeli officials continue to signal that this is just the beginning.
