KABUL, Afghanistan (AP) — In a phone call with U.S. Secretary of State John Kerry, Hamid Karzai accused Pakistan of being behind a recent series of attacks and of blocking his government from striking a peace deal with the Taliban, the Afghan president’s office said Sunday.

Karzai routinely makes such accusations against Islamabad, but his tone in recent days has been particularly pointed and direct. They come after three attacks in five days in the capital Kabul, the latest coming on Saturday when assailants fired machine guns and rocket-propelled grenades at the country’s electoral commission ahead of next week’s general election.
