Karzai routinely makes such accusations against Islamabad, but his tone in recent days has been particularly pointed and direct. They come after run of three attacks in five days in the capital Kabul, the latest a Saturday machine-gun and rocket-propelled grenade barrage of the country's electoral commission ahead of general elections set for next week.
Karzai told Kerry yesterday the attacks were complex in nature and stage-managed by "foreign intelligence agencies," a reference to Pakistan's Inter-Services Intelligence.
The Taliban have claimed responsibility for the recent violence in Kabul. Islamabad has a long and complicated relationship with the group, but few analysts accept Karzai's allegations that Pakistani intelligence agencies and not the Taliban are staging attacks. Pakistan denies that it is assisting the Taliban.
Karzai is not allowed to run for re-election in the April 5 ballot, as he is barred by the constitution from seeking a third term in office. He is seen as positioning himself for life after the presidency, depicting himself as a tough-speaking nationalist.
Despite widespread support for the agreement, Karzai says he first wants the US to move forward with a peace pact with the Taliban, presumably by putting pressure on neighbour Pakistan.
During the telephone conversation, according to the Afghan presidency, Karzai told Kerry that the Taliban were willing to talk to his High Peace Council, an 80-member body tasked by the president to spearhead reconciliation with his armed opposition, but Pakistan was preventing them.
