The US has asked Pakistan to hand over Osama Nazir, a key suspect in church attacks and the second attempt on President Musharraf's life, sources told Daily Times on Wednesday. Intelligence agencies arrested Nazir in Faisalabad last week and have been questioning him since. Nazir allegedly supervised an attack on a church in the diplomatic enclave in Islamabad that killed five people, including two US citizens. Thirteen US citizens were wounded in the attack.
