Egypt launched air strikes in the Sinai region close to the border with Israel on Wednesday, killing more than 20 suspected Islamic terrorists and marking the largest Egyptian military operation in the Sinai since the 1973 Yom Kippur War.
The air strikes on positions in the town of Sheikh Zouaid followed the deaths of 16 border guards last Sunday in an attack blamed partly on Palestinian terrorists.
Witnesses in Sheikh Zouaid, about 10 km (six miles) from Gaza, said they saw two military jets and heard sounds of explosions. Other witnesses in a nearby area said they saw three cars hit.
The strikes followed clashes between armed men and security forces at several security checkpoints in the Sinai region.
