Even as Syria is making steady progress in delivering, as promised, chemical weapon precursors to the Organisation for the Prohibition of Chemical Weapons, the U.S. ambassador to the UN is foaming from her mouth about alleged Syrian stonewalling. Syria had explained certain delays in earlier deliveries with attacks by insurgent groups on chemical weapon sites and convoys. The U.S. certainly knows that such attacks happened and continue to happen.

Phil Sands has written several good stories about the attack on Syria for the UAE National. His latest is about an attack by insurgents, western supported ones including the Al-Qaeda franchise Jabhat al-Nusra, on a chemical weapons depot in Syria near the border to Jordan. The "western" insurgency command center in Jordan feared that the insurgents could seek those. It ordered the insurgents to stop and withheld weapons and ammunition to make them do so:

International military commanders based in Jordan were on the brink of ordering air strikes against a “strategic weapons” store in southern Syria, according to accounts of a dramatic incident last week.

With rebels closing in on the fortified bunker at the Tal Al Jabiyeh military complex in south-western Deraa, military and intelligence officers from the US, Europe and Arab states who staff a clandestine operations room in Amman, scrambled to make sure the weapons inside did not fall into the hands of Al Qaeda-affiliated rebels.
…
In a tense four-hour period on Tuesday night last week, rebels involved in the assault – including Jabhat Al Nusra – were warned by officials in the command centre that Israeli jets were on standby to bomb a bunker on which they were advancing, less than 8km from the border with Israel.

It is not surprising that the "western" led command center in Jordan is coordinating with the Israeli military. As Phil Sands reported earlier the Israeli military is paying large sums to some of the mercenary groups:

At least three rebel factions in southern Syria have been in regular contact with Israeli intelligence officials, and have each received more than one tranche of funding worth hundreds of thousands of dollars, according to a well-connected rebel commander who is familiar with operations in the zone bordering Jordan and Israel.

“When they run out of cash, they contact the Israelis,” he said of fellow commanders in the area, a practice he said did not bother him.

The fighting in the south of Syria, coordinated largely by the United States from Jordan, does not only include Jabhat al-Nusra, but also the competing (former) al-Qaeda franchise ISIS:

The Syrian government and its Lebanese allies from the Hezbollah militant group announced last November that they’d launched an operation to clear the mountainous Qalamoun – including the key rebel-held city of Yabroud – in order to take control of the country’s main highway and break a key rebel supply route that links rebel strongholds in central Syria with the pro-rebel Lebanese city of Arsal.

But progress has been slow, as hundreds of ISIS fighters, as well as a unit of radical fighters from Saudi Arabia, have bolstered the rebel forces, according to Syrian activists who maintain close contact with radical groups that are fighting to topple the regime of President Bashar Assad.

In another development, little mentioned in "western" media, Jabhat al-Nusra broke the truce that had allowed the United Nations to distribute food in the Yarmouk refugee camp near Damascus:

The peace agreement apparently has fallen apart. Nusra, according to some reports, has returned to the area, and pro-government forces are apparently fighting to prevent them from re-establishing themselves.

One can only speculate about why Nusra came back. Maybe its leaders realized that their pullout could be seen as a victory for the government. Maybe they simply couldn’t give up an area that is strategic to the control of southern Damascus. But whatever the reason, Nusra has returned, and the optimism that life could return to normal in Yarmouk appears to have vanished.

Other than the Yarmouk disaster little progress seems to have been made on either side of the fighting. The announced U.S. supported spring offensive by the insurgents in the South seems not have happened yet or is simply stuck while the Syrian army offensives in Qalamoun and in Aleppo are only slowly progressing.
