According to the report, which cited unnamed sources in the US National Security Agency, top-ranking members of the Islamic terror group recently participated in a conference call in which various methods of attacking railways in Europe were extensively discussed, including planting bombs in tunnels or on the trains themselves and sabotaging train tracks and electrical systems.
During the fighting in Breiqa Saturday, six mortars fired from Syria landed inside Israel, causing no damage or injuries. Israel retaliated by firing a Tamuz missile at the Syrian military post from which the fire emanated.
Egyptian authorities on Monday were on high alert after suspected Islamist militants killed at least 24 Egyptian policemen in the Sinai peninsula, where attacks on security forces have multiplied since the army overthrew Islamist President Mohamed Morsi on July 3.
Egyptian daily Al-Ahram quoted security officials as saying that military and police have declared a state of emergency in northern Sinai, deploying roadblocks in the area in an effort to combat terrorists.
The official was quoted as saying it is thus far unclear how many militants took part in the ambush. Three policemen were also wounded in the grenade and machine-gun attack near the north Sinai town of Rafah on the border with Israel. AFP reported that Egypt had resealed the border crossing into nearby Gaza in the wake of the ambush.
Mounting insecurity in Sinai also worries the United States because the area lies next to Israel and the Hamas-ruled Gaza Strip, as well as the Suez Canal.
