KABUL - Afghanistan said on Sunday it was pulling out of security talks in Islamabad in anger at alleged cross-border attacks, which it claimed were designed to disrupt the second round of its presidential election.

It said the attacks were "aimed at disrupting the second round of presidential elections", due to be held on June 14.

Local leaders claimed that rockets fired from Pakistani territory had left six dead and around 40 injured in recent days. There was no independent verification of the claims.

The National Security Council said it would "raise serious concerns" with Pakistan through the foreign ministry, according to the statement.

In protest, Afghan security officials will not participate in a regional security summit due to take place in Islamabad on June 4. (Monitoring Desk)
