Pakistan ? Pakistan’s pro-U.S. president signed a regulation late Monday to put a northwestern district under Islamic law as part of a peace deal with the Taliban, going along after coming under intense pressure from members of his own party and other lawmakers.

Asif Ali Zardari’s signature was a boon for Islamic militants who have brutalized the Swat Valley for nearly two years in demanding a new justice system. It was sure to further anger human rights activists and feed fears among the U.S. and other Western allies that the valley will turn into a sanctuary for militants close to Afghanistan.

Whatever criticism may come, Zardari can claim some political cover — the National Assembly voted unanimously Monday to adopt a resolution urging his signature, although at least one party boycotted. Earlier, a Taliban spokesman had warned lawmakers against opposing the deal.

Zardari’s spokeswoman, Farahnaz Ispahani, confirmed the president signed the regulation Monday night.
