Two blasts, within minutes of each other, are being blamed for at least seven deaths in Pakistan, including a prominent Islamic cleric.
Pakistani officials say the suicide bombers targeted mosques in the eastern city of Lahore and the northwestern town of Nowshera shortly after Friday prayers.
Police say in Lahore a teenage bomber slipped into a seminary next to mosque and blew himself up, killing Sarfraz Naeemi, a prominent cleric who openly supported the military crackdown on the Taliban. Two others also died.
In the second attack, in Nowshera, a bomber rammed a vehicle filled with explosives into a mosque near an army depot, killing at least four and wounding close to 100 people.
Following the Lahore blast, stunned seminary students stood outside, chanting anti-Taliban slogans.
The attacks also drew condemnation from Pakistani leaders.
