Fears of a terrorist strike against Western embassies in Yemen have grown amid claims a convoy of lorries laden with explosives had been smuggled into the country's capital city, Sana'a.
In an apparently botched surveillance operation, militants driving six trucks filled with weapons and ordnance succeeded in giving security forces the slip as they entered the city, according to local media.
The revelations came as western diplomatic missions in Sana'a went into lockdown following threats from al-Qaeda's Yemeni affiliate, which has taken responsibility for a failed attempt to blow up an airliner over Detroit on Christmas Day.
Both the British and American embassies, considered the most high-profile targets in the city, remained closed for a second day. France and the Czech Republic also shut their embassies, while Spain, Germany and Japan announced restrictions on public access to their missions.
The identity of those who smuggled the weapons contingent into Sana'a has not been disclosed, and it is unclear if its disappearance is linked to al-Qaeda's increasingly powerful Yemeni branch, al-Qaeda in the Arab Peninsula (AQAP)
Although AQAP released a statement on Sunday urging its followers to kill all Western diplomats on the Arab Peninsula, western officials have declined to divulge whether or not threats of a specific nature have been made. It is not the first time that lorries carrying arms have disappeared in Yemen, and sources suggested that the weapons may well have been bound for tribal rebels in the North. The insurgents, who are Shia, are regarded as apostates by al-Qaeda, although some observers say there may be a limited alliance of convenience between the two.
