An explosion struck a gas pipeline in Egypt's Sinai peninsula on Saturday, following a wave of attacks on security checkpoints in the region, Reuters reported.
No-one claimed responsibility for the pipeline explosion, or the attacks on checkpoints and it remains unclear whether the violence is related to the overthrow of Egyptian President Mohamed Morsi.
The pipeline supplies gas to Jordan and has been attacked 10 times since former President Hosni Mubarak was ousted in the January 25 Revolution in 2011.
A Coptic Christian priest was killed on Friday in the region by a group of militants, whilst a group of militnats killed five security officers at a checkpoint the same day.
Egypt has failed to take control of the Sinai peninsula since Mubaraks departure, with militants attacking security forces and launching rocket attacks at Israel.
