Syrian conflict escalates, now Iran v Pakistan?

Iran's interior minister has warned it may send forces into Pakistan if it does not act to free five Iranian border guards seized 10 days ago.

The men are thought to have been taken into Pakistan after being captured in Iran's Sistan Baluchistan region.

Abdolreza Rahmani-Fazli demanded that Islamabad treat the case "strongly and seriously" and "take the necessary measures" to secure their release.

The Sunni militant group Jaish al-Adl has said it was behind their capture.

The group has posted what it said were photographs of the guards, bound and being held in an unknown location.

A video broadcast by al-Arabiya TV on Friday purportedly showed one of the men, Sgt Jamshyd Danaifard, saying they were "safe and sound".

He added that Jaish al-Adl wanted the Iranian authorities to exchange 300 Sunni prisoners in Iran and its close ally Syria for the guards.
