Police from a Christian-majority region of the Philippinesinfo-icon has proposed issuing mandatory identification cards to thousands of Muslims of the region, reported The Guardian.Authorities in Central Luzon, a region north of the capital, were quoted in local mediainfo-icon as saying the policy was a counter-terrorism measure after Islamist militants took over a city hundreds of kilometres to the south on the island of Mindanao.

The issue was discussed at a meeting between police, military and political figures and about 200 Musliminfo-icon religious and community leaders at the provincial capitol building, according to news outlet Rappler.

Chief Superintendent Aaron Aquino said the ID cards would allow authorities to identify and weed out undesirable individuals and terrorists, Rappler reported.

He said the system had already been implemented in the town of Paniqui "and we want this to be replicated in all Muslim communities in the whole region for easy and efficient identification of our Muslim brothers and sisters".

Government forces have been hammering the city of Marawi in the south for nearly two months after local militant factions, who claim allegiance to Isis, rampaged through and took control.

Philippine sectarian bloodshed unites Muslims and Christians

President Rodrigo Duterte has imposed martial law across Mindanao and had to apologise after blaming the residents of Marawi by saying they allowed Isis sympathisers to stay.

Human Rightsinfo-icon Watch said authorities were threatening to "single out Muslims" with ID cards, violating the rights to equal protection of the law and freedom of movement.

"Requiring Muslim-only IDs in response to a perceived failure of Muslims to prevent Islamist fighters from entering Marawi City is a form of collective punishment," the New York-based advocacy group said in a statement.

It added that reports of some Muslim leaders present at the meeting not rejecting outright the compulsory ID cards were "irrelevant from a rights perspective" for the roughly 26,000 Muslims living in Central Luzon region. "ID requirements for Muslims should be rejected outright."
