A Pattern of Containment

First, it was this report from March 10th:

Iranian weapons en route to Taliban have been seized by International Security Assistance Force (Isaf) in the border city of Nimroz.

The weapons include 48 rockets with a range of 20 kilometers, officials have said.

The seized rockets reportedly double the usual range of the rockets used by the Taliban.

On March 15th an Iranian ship was seized, followed on March 16 with details:

The “Victoria”, The ship seized by Israel allegedly en route from Iran to militants in the Gaza Strip on Tuesday contained tons of weapons include six C-704 anti-ship missiles in ready-to-be launched containers, was presented today to the International press.

Also on March 16, a false alarm in Turkey:

An Iranian cargo plane flying to Syria was ordered to land in south-eastern Turkey amid reports it may have been carrying military material.

A lengthy search at Diyarbakir airport found the plane was carrying 150 tonnes of food; it was allowed to leave on Wednesday afternoon.

Then this report from March 17:

South Korea and Singapore have intercepted suspected nuclear and weapons materials bound for Iran that breach UN sanctions imposed on the Islamic republic, diplomats said on Thursday.

The two seizures, made in the past six months but only revealed now, add to a growing list of alleged Iranian attempts to breach an international arms embargo, which are bringing mounting pressure to tighten sanctions, they said.

Also on March 17 in Malaysia:

Police quizzed 34 people after seizing parts and equipment believed meant for making weapons of mass destruction, including nuclear warheads, from two containers on March 8.

The parts were from China and bound for Iran, said Inspector-General of Police Tan Sri Ismail Omar.

Commenting on theSun’s front page report today, he said among those questioned were the captain and crew of the merchant freighter Bunga Raya I belonging to the Malaysian International Shipping Corporation Berhad.

On March 31 Turkey searched another plane with different results:

The report to the council's Iran sanctions committee, which oversees compliance with the four rounds of punitive steps the 15-nation body has imposed on Iran over its nuclear program, said a March 21 inspection turned up the weapons, which were listed as "auto spare parts" on the plane's documents.

The plane was bound for Aleppo, Syria, and was given permission to pass through Turkish airspace provided it made a "technical stop" at Diyarbakir airport, the report said.

The intelligence activities involved in this type of consistency are noteworthy.
