Barack Obama calls for a purge on the world's nuclear weapons. His warnings of proliferation were accompanied by the possibility of nuclear-armed terrorists. He unveiled a plan to cut stockpiles, curtail testing, choke fissile production and secure loose nuclear material. "As the only nuclear power to have used a nuclear weapon, the United States has a moral responsibility to act," he said. His speech was warmly received.

At least seven people have died after militants attacked the U.S. consulate in Peshawar. Several explosions were reported near the consulate, and some of the area's other buildings collapsed. A susequent gun battle between the police and attackers occured after the explosions, and eleven people were killed in those. One of Pakistan's main Taliban factions has said it carried out the attack. The raid came a few hours after forty-three people had been killed in a suicide attack about fifty miles north-east of Peshawar. That bomber had targeted a crowded rally that was being held by a Pashtun nationalist party in Timergara.
