48 Hours... 48. Hours.

We're starting to hear in the first results of the latest war, now expanded to Syria:

At least 120 militants militants and eight civilians were killed in the US-led strikes, according to the British-based Syrian Observatory for Human Rights, which monitors military activity in Syria. It said 70 of the killed militants were from Isis, while the other 50 it described as being aligned with the Nusra Front, the parent organization of the Khorasan cell.

About 100 critically injured fighters were taken to Iraq for treatment, it added.The Observatory also said there had been eight civilian casualties, included three children. Its reports could not be independently verified.

Obama was scheduled to arrive at the UN headquarters in New York later on Tuesday, with an intensive diplomatic push to garner support for the war already underway. On Wednesday, Obama will address the UN General Assembly and chair a meeting of the UN security council, pushing for a binding resolution against Isis, including an international travel ban on foreign fighters travelling from other countries.

Although the UK did not participate in Tuesday’s strikes, prime minister David Cameron expressed support for military action. Russia, Syria’s main international ally, which like the UK is a permanent member of the UN security council, denounced the US-led strikes as a violation of Syria’s sovereignty.

Iran also questioned the legality of the US-led air strikes. The Wall Street Journal quoted President Rouhani as saying that the strikes amounted to an attack because they were not approved by the UN or Syria.

However, Washington believes the support of the five Sunni Arab allies, an alliance that appears to have been pulled together in the 48 hours leading up to the strikes, are critical to legitimacy of its expanded war against Isis.

Hours after the strikes began, General Martin Dempsey, chairman of the US joint chiefs of staff, told a small group of reporters accompanying him on a flight from flight to Washington from Europe that Arab support was indispensable, saying “I can’t overstate” the importance of the five Sunni allies.

“We now have a kind of credible campaign against Isil that includes a coalition of partners,” he said, according to the Associated Press.
