Egypt hits 'jihadist camps' after attack on Coptic Christians

Egyptian forces have struck "terrorist training camps" in retaliation for an attack on Coptic Christians, President Abdul Fattah al-Sisi has said.

State media say six strikes hit the town of Derna in neighbouring Libya.

Gunmen earlier attacked a bus carrying worshippers in central Egypt, killing at least 28 people and wounding 25 others.

President Sisi said he would "not hesitate to strike terrorist camps anywhere".

Announcing the strike in a TV speech late on Friday, he promised to "protect our people from the evil".

Countries supporting terrorism should be punished, he said, as he appealed to US President Donald Trump for help.

Military sources told Reuters news agency that the militants targeted in Libya had been involved in the attack on Egyptian Christians earlier in the day.

Although no group immediately said it was behind the attack, Islamic State (IS) militants have targeted Copts several times in recent months.

Libya is effectively controlled by a large number of armed militias that have emerged in the chaos since Nato-backed forces overthrew long-serving ruler Col Muammar Gaddafi in October 2011.

But IS has also built a presence in Libya during the chaos.
