CAIRO - An Egyptian soldier was killed on Sunday when militants attacked the bus he was driving in the town of Al-Arish in the Sinai Peninsula, an army source said.
The bus was transporting police officers, three of whom were wounded, the source said.
There was no immediate claim of responsibility for the attack.
Sinai-based militants have stepped up violence against the state since the army ousted Islamist President Mohamed Morsi in July, killing more than 400 soldiers and police, according to the Foreign Ministry.
The attacks have spread to Cairo and other cities in recent months.
