Egyptian President Abdel-Fattah el-Sissi said Wednesday that the Russian plane that crashed in Sinai last year was downed by terrorists seeking to damage Egypt's tourism industry and relations with Moscow.

"Has terrorism ended, no it has not but it will if we unite. Whoever downed the Russian plane, what did he mean? He meant to hit tourism, and to hit relations with Russia," el-Sissi said in a televised speech.

The comments were the first official Egyptian indication that the plane was deliberately downed.

Moscow stopped all civilian flights to Egypt, a popular destination for Russian tourists, after a Russian airplane crashed in Sinai Oct. 31 killing all 224 people on board.

Russia said a bomb brought down the flight and the Islamic State group said it smuggled the explosive aboard concealed in a soft drink can. But an Egyptian-led investigation had said it has yet to find evidence of foul play.

The official Egyptian confirmation that a bomb brought down the Airbus A321 could potentially expose Egypt to compensation payments to the families of the victims.
