Egypt hunts down militants

EGYPTIAN troops and police on Tuesday raided homes in search of suspects in an attack that killed 16 soldiers on the border with Israel and prepared to close smuggling tunnels to Gaza, security officials said.
An AFP correspondent witnessed large trucks loaded with bulldozers headed to Rafah, a town on the border with the Palestinian Gaza Strip that sits atop a honeycomb of smuggling tunnels.
"There are preparations to close the tunnels," a security official said.
Officials said soldiers and police raided several homes near the north Sinai town of El-Arish in search of known Islamist extremists who might be linked to Sunday's attack, the deadliest such ambush in decades.
