@guardian: This is the voice of Mahmoud Shalabi, Gaza director for Medical Aid for Palestinians, describing the ‘vicious’ attacks that took place in Gaza during a 36-hour near-total communications blackout imposed by Israel. At the same time as communications were lost on Friday evening, Israel intensified its aerial bombardment and launched its initial ground operation into the Gaza Strip following Hamas’s attack on southern Israel more than three weeks ago. Over the weekend, ambulance drivers in Gaza described how they decided to just drive towards the sound of explosions as there were no accurate coordinates to follow. “There was a total electricity blackout. And every once in a while the sky would turn into an orange colour from the severity of the explosions that were happening,” says Shalabi. “I can't as a humanitarian even do my work. I can't help the people who are still standing in the north of Gaza. I'm asking for safe corridors. I'm asking for the ceasefire and for this bloodshed to stop.” A World Health Organization official said on Tuesday that a “public health catastrophe” was imminent in Gaza amid overcrowding, mass displacement and damage to water and sanitation infrastructure.
