Egypt has arrested a veteran of the Syrian civil war on suspicion of planning terrorist acts inside Egypt, the state news agency reported on Sunday. The Egyptian prosecutor's ****** in Suez City ordered the arrest of Wael Ahmed Abdel Fattah for 15 days, MENA reported, adding that he was suspected of working with Islamist militant groups. MENA said Abdel Fattah, a former oil company employee, battled in Syria alongside the Nusra Front, seen as the most effective rebel group fighting Syrian President Bashar al-Assad. Since the army toppled President Mohamed Mursi of the Muslim Brotherhood last July, Islamist militants based in the Sinai Peninsula have stepped up attacks on police and soldiers, killing hundreds.
