A senior member of the Palestine Liberation Organization rapped Washington for its attempts to meet its interests at the cost of the lives of innocent people, and said the US insatiable expansionism is pushing the train of war towards Syria. \"The US expansionism and its emphasis on protecting its interests at any possible cost is the root cause of the threats of military attack against Syria,\" member of the PLO\'s Executive Committee Taysir Khalif told FNA on Tuesday. He lashed out at the White House for its double-standard policies on democracy and human rights in different parts of the world, and said, \"What matters for Washington is just the protection of its interests and it plans for aggression and attack against other countries due to the very same reason.\" Khalif said a US attack on Syria is very likely, and continued, \"The US may materialize its threat but it cannot take the control of affairs in its hands and get rid of the headache it has created for itself (in Syria).\" In relevant remarks, Supreme Leader of the Islamic Revolution Ayatollah Seyed Ali Khamenei has also warned of the dire consequences of any military intervention in Syria for the region, and said the US will certainly be severely harmed by pursuing warmongering policies against the Muslim country. \"The US threats and possible intervention in Syria is a disaster for the region and if such an act is done, certainly, the Americans will sustain damage like when they interfered in Iraq and Afghanistan,\" Ayatollah Khamenei said in a meeting with members of the new Iranian cabinet in Tehran last week. He cautioned the US and its allies that their military intervention in Syria would yield no result but blazing fire and increasing nations\' hatred from them. Ayatollah Khamenei warned the US and its allies that \"starting this fire will be like a spark in a large store of gunpowder, with unclear and unspecified outcomes and consequences\".
