A Nour Party parliamentary candidate was hospitalised on Tuesday after two men forced him out of his car and attacked him.
Mahmoud Abdel-Hamid, who is running for an individual seat in Gharbiya governorate and is a member of the Salafist party, was forced out of his car by two men riding a motorcycle.
Abdel-Hamid, 42, was taken to Kafr El-Sheikh hospital suffering from severe head injuries, internal bleeding and a concussion.
The incident comes two days after another Nour Party candidate, Mostafa Abdel-Rahman, was shot dead on Saturday while leaving his house in the North Sinai city of Al-Arish.
The two men who assaulted Abdel-Rahman were also riding a motorcycle.
The Nour Party is the only Islamist party that supported the ouster of Muslim Brotherhood president Mohamed Morsi in July 2013. They are also the only Islamist group participating in the ongoing parliamentary elections in Egypt.
The long-delayed parliamentary elections began last week, with voters in 14 of 27 governorates heading to the polls.
Voters in the remaining 13 governorates, including Gharbiya, North Sinai, and Cairo, will go to the polls on 22-23 November.
