A fifth US Navy destroyer is on its way to the eastern Mediterranean as international concerns grow over Washington and its allies ' intentions to bomb Syria.

The US has already beefed up its military presence in the eastern Mediterranean.

According to media reports, four US warships and a submarine are in the region and a fifth is on the way. All destroyers are cruise - missile equipped.

The US is rushing to attack Syria over an alleged chemical attack in Syria, before results of UN investigations over the story are final.

The Obama administration, backed with Israeli intelligence services, says it has concluded that the Syrian army has used chemicals near Damascus.

US claims come as Syria has already provided UN with evidences on at least three chemical attacks carried out by US - backed militants near the Syrian capital.

Israeli intelligence information is widely believed to have played a central role in paving the way for justifying US attack on Syria.

The US has conspicuously insisted that the story is “undeniable” even though they have never presented any proof of it, but the secret “proof” which is never put forth for public scrutiny apparently comes straight from Israeli intelligence.

Israeli military intelligence told the US they had wiretapped the Syrian government and heard them talking about using chemical weapons, insisting that “proved” that they were the ones who did it.

A large delegation of senior Israeli security officials is currently in Washington holding talks with top administration officials led by US National Security Adviser Susan Rice.

Israel has been pushing these stories multiple times, always citing dubious secret evidence that the public never gets to see.
