Bombings on the eve of Pakistan's landmark election have killed at least four people and wounded 18 others.
The four died in a blast Friday near political party offices in North Waziristan, a Taliban and al-Qaida stronghold. Earlier reports had put the death toll at five. Thirteen people were wounded.
A blast in the southwestern part of the country wounded five more people outside an office being used by the Pakistan People's Party.
No one has claimed responsibility for the bombings, but the Taliban have carried out numerous attacks to undermine the polls and say they have dispatched suicide bombers for the national election. More than 100 people have been killed and scores wounded since late April.
Pakistan's military says it is deploying thousands of troops to polling stations and counting centers.
The recent bombings of two rallies of a leading Islamic party, Jamiat Ulema-e-Islam, strengthened views the Taliban is opposed to democracy and is targeting anyone taking part in the elections.
