The mayor's home in the Libyan city of Derna has been burnt down, as hundreds of protesters demanded answers for last week's catastrophic flood. They gathered on Monday night at the city's landmark Sahaba Mosque, many chanting for top officials in Libya's eastern government to be sacked. On Tuesday, the day after the protests, a minister in eastern Libya's government announced that all journalists had been asked to leave Derna, and accused them of hampering the work of rescue teams. Monday's rallies at the Sahaba Mosque - itself partially damaged by flooding - were the biggest seen since the floods hit, and there are suggestions the protest has some institutional backing. Claudia Gazzini of International Crisis Group in Libya told BBC Newsday.
