BEIRUT - Lebanon's prime minister threatened to resign on Sunday, warning rival parties in his unity cabinet that the state faced collapse because of paralysis that has come to a head with its failure to resolve a crisis over rubbish disposal.Protesters called for a second day of demonstrations against Prime Minister Tammam Salam's cabinet on Sunday after at least 35 people were injured on Saturday night when security forces used water cannons and tear gas to disperse several thousand demonstrators in central Beirut.Salam's government has suffered almost complete paralysis since it took office last year as wider crises in the Middle East, including the war in neighboring Syria, have exacerbated Lebanon's own political and sectarian divisions.
