ISLAMABAD (AP) — Neighbors Pakistan and Iran on Wednesday pledged to enhance efforts at a “united front” against Afghanistan-based militants, saying their presence poses a serious threat to regional and global security.

The countries, which share a long and porous border, made the commitment in a joint statement issued after a three-day visit by Iran’s President Ebrahim Raisi to Islamabad.

The visit was aimed at mending ties that were strained in January when each carried out strikes in the other’s territory, targeting militants accused of attacking security forces.

The Iranian president met with Pakistani President Asif Ali Zardari, Prime Minister Shehbaz Sharif and other officials, including powerful army chief Gen. Asim Munir.

The joint statement said the two sides “reaffirmed their willingness to enhance cooperation on counter-terrorism and security and to develop a united front against terrorism.”
