The Egyptian military killed 23 extremists in dawn raids Thursday in northern Sinai, security officials said, a day after Islamic militants attacked army positions in the restive peninsula and set off the bloodiest fighting in decades. The raids took place just south of the border town of Rafah, a key Sinai border town near the Gaza Strip, said the officials. \
