MANILA, Philippines (Dispatches) -- The Philippine Congress voted overwhelmingly Wednesday to approve President Rodrigo Duterte's request to extend martial law in the south by a year after the military warned that terrorist threats continue to lurk in the region despite the defeat of a disastrous pro-Daesh group siege.
A majority of the Senate and the House of Representatives - with 240 voting to approve and 27 opposing - backed the extension of martial law across the Mindanao region through the end of 2018. The vote followed warnings by Defense Secretary Delfin Lorenzana and other officials that Daesh-linked militants were trying to recover from their defeat in southern Marawi city and were plotting new attacks.
"The rebellion has not stopped, it has just moved to another place," Lorenzana told senators and House members in a special joint session.
Several lawmakers from the south backed martial law, saying it would prevent a repeat of the bloody Marawi siege and foster the Islamic city's rebuilding.
Five months of intense fighting, including daily airstrikes and artillery bombardment by the military on hundreds of militants, left more than 1,100 combatants and noncombatants dead and displaced about half a million people, turning mosque-studded Marawi's central business and residential districts into a smoldering war zone.
Lorenzana said it would take at least three years to rebuild Marawi, a bastion of Islamic faith in the predominantly Roman Catholic Philippines.
Opponents argued that extending martial law in the south is unconstitutional because it's an "extreme measure" that can only be imposed when actual rebellions against the government exist. They expressed fears that such a move can be a prelude for Duterte to declare martial law throughout the Philippines.
Sen. Francis Pangilinan, who heads the main opposition Liberal Party, rejected the martial law extension, saying it did not have a clear constitutional basis. He cited the government's declaration that the terrorists have been defeated in Marawi, and said that major rebel attacks have been dealt with by past presidents without resorting to martial rule.
"We will be in danger of becoming the monsters that we seek to defeat, those who have no regard for law, order or respect for the constitution," Pangilinan said.
Opposition Rep. Tom Villarin said the remaining threats posed by militants in the south could be addressed by law enforcers without martial law and added that scheduled local elections in the south could be endangered by Duterte's declaration. Another opposition legislator, Edgar Erice, warned that the Philippines risks being regarded as a "banana republic" if officials flaunt the constitution.
