Three bombs in Pakistan’s restive southwestern province of Baluchistan have damaged a power line and a shop, but caused no casualties, officials say.
Police investigate two large blasts heard near Pakistan’s capital.
Rawalpindi houses the headquarters of Pakistan’s army and the residence of Parvez Musharraf, the president.
The blasts came as Pakistan was engaged in a military operation against the Taliban in its northwest tribal regions.
A month earlier, a car bomb killed at least six people near the Danish embassy in Islamabad.
