Poll rigging and exchange of fire between rival groups disturbed voting in different constituencies of National Assembly and provincial assemblies on Saturday.
At least three people were injured in Mianwali (Punjab) and Mardan (KP) as rival groups clashed. However, the polling was continued in Mianwali due to meddling of elders.
Incidents of violence have been reported from NA-140 Kasur (Punjab), PP-44 Mianwali (Punjab) and NA-168 Vehari (Punjab), NA-9 Mardan (KPK) where exchange of fire happened between the rival political groups.
Voting in Vehari and Mardan could not be resumed after the clashes.
Law and order situation also remained tense in PS-57 Badin where armed men moved freely in polling booths.
Bogus voting was continued in NA-155 Rahim Yar Khan where voters cast votes on expired, color copies and Photostats of National Identity Card (NIC).
By-polls were held on six National Assembly seats, mostly fell vacant after PPP, ANP and PML-N lawmakers resigned to join the Imran Khan-led PTI, and four provincial assembly seats, two each in Punjab and Sindh.
