Egypt's president speaks to Putin after Moscow says bomb caused last month's plane crash

Egyptian President Abdel-Fattah el-Sissi has told Russian President Vladimir Putin that Egypt understands the Russian people's pain, a day after Moscow said an onboard bomb caused last month's plane crash in Sinai.

Egypt's presidential spokesman Alaa Yousef confirmed the two leaders spoke by phone Wednesday in a statement that made no mention of a bombing. Egyptian officials have declined to say whether a bomb caused the crash, saying a multi-national investigation is still underway.

Russia's FSB security service said Tuesday that a bomb brought down the plane in Egypt's Sinai Peninsula, killing all 224 people onboard. The Islamic State group claimed the attack.

Suspicions that a bomb caused the crash have led to flight cancellations to and from Egypt and dealt a major blow to its vital tourism industry.
