Islamist gunmen kidnap seven Egypt security personnel in Sinai

 Hardline Islamist groups based in North Sinai have exploited the collapse of state authority after the 2011 uprising that toppled Hosni Mubarak to launch attacks across the border into Israel and on Egyptian targets.
The gunmen are demanding the release of members of Islamist group Al-Tawhid wal Jihad who were convicted of carrying out attacks in North Sinai in 2011 that killed six members of the security forces and a civilian, a security official said.
