LONDON — The leaders of Afghanistan and Pakistan said Monday they would push the Taliban to come to the table for peace talks to end Afghanistan’s protracted war and gave themselves a six-month deadline to get a deal.

British Prime Minister David Cameron hosted Afghanistan’s President Hamid Karzai and Pakistan’s President Asif Zardari for trilateral talks on Afghanistan’s floundering peace and reconciliation process. The leaders believe the Taliban are softening their hard-line stance against discussions.
