Alwaght- As investigators suspect that a bomb brought down the Russian plane which crashed over Sinai region in Egypt, intelligence sources in Moscow solidly names Saudi Arabia as responsible for the bombing which killed 244.

Veterans Today website quoted Russian intelligence sources as saying Saudi regime  spies planted  the bombing  on the ill fated flight with Egyptian intelligence fully complicit in the terror attack.  The sources stated: “Half the Egyptians work for Israel, the other half for Saudi Arabia anyway, Egypt has no security services, only paid foreign spies.”

Sources in Moscow say there no doubts whatsoever. “Would the Saudis attempt something like this in Israel’s backyard without involving them somehow? What do you think? Would they do it without the US knowing, when it has guaranteed to protect their security? Inquiring minds would like do know.”

Meanwhile, the head of the joint investigation team said Saturday that a noise was heard in the last second of the cockpit voice recording from the Russian plane that crashed last week in Egypt's Sinai Peninsula .

However, Ayman el-Muqadem warned it was too early to say what caused the plane to apparently break up in mid-flight. Analysis of the noise was underway.

"All scenarios are being considered ... it could be lithium batteries in the luggage of one of the passengers, it could be an explosion in the fuel tank, it could be fatigue in the body of the aircraft, it could be the explosion of something," said El-Muqadem, who is Egyptian and leading the investigation committee that includes experts from Russia, France, Germany and Ireland, where the plane was registered. El-Muqadem appeared alone at the news conference in Cairo.

ISIS terrorist group claimed they brought down the Metrojet flight, without offering proof, saying it was in retaliation for Moscow's airstrikes that began a month earlier against fighters in Syria.

El-Muqadem said debris was found scattered across a 13-kilometer (8-mile) stretch of desert, indicating the Airbus A321-200 broke up mid-air, but initial observations don't shed light on what caused it. Some pieces of wreckage were still missing, while the recovered pieces will be taken to Cairo for analysis, he said.

Also Saturday, Egypt's foreign minister complained that Western governments had not sufficiently helped Egypt in its war on terrorism.

Egypt's past calls for assistance and coordination on terrorism issues from "the countries that are now facing the danger" had not been dealt with seriously, Sameh Shoukry told a news conference. "European countries did not give us the cooperation we are hoping for," he said.
