 White-spread destruction was seen around Gaza on October 10 morning, as relentless Israeli air raids continued to bombard the enclave, killing at least 680 people.The latest round of airstrikes came after Hamas threatened to execute an Israeli captive every time Israel bombed a Palestinian home without warning. Israel said on Tuesday it had re-established control over the Gaza border and was planting mines where Hamas militants had toppled the barrier during their bloody weekend assault. The military also called up an unprecedented 300,000 reservists and imposed a blockade on the Gaza Strip, raising fears it planned a ground assault in response to the most audacious and deadly Hamas attack in decades.
