Authorities in northwestern Pakistan say the death toll from twin bombings in the city of Peshawar late Saturday has reached at least 34.

Local authorities say more than 90 people, including several journalists and police, were wounded in the explosions. They say the first blast was relatively small and drew police, rescue workers and onlookers to the site. A large explosion rocked the area minutes later, causing the casualties.

The nature of the blasts is not known and no one has claimed responsibility.

The explosions came after Afghan President Hamid Karzai and CIA Director Leon Panetta visited Islamabad. Mr. Karzai called on Pakistan to eradicate militant safe havens from tribal areas along the Afghan-Pakistani border, while Panetta discussed ways to strengthen future intelligence sharing.
