The Bureau of Investigative Journalism reports: Two suspected US drone strikes have killed up to 12 civilians in the south of Yemen.

Reports vary but between 14 and 15 people have been killed in a double air strike on the southern city of Jaar. Of these, as many as a dozen are being reported as civilians. Up to 21 civilians have also been reported injured.

Witnesses said the first strike targeted alleged militants meeting in a house. Civilians who had flocked to the impact site were killed in a follow-up strike. Although the attack is unconfirmed, if accurate this tactic would echo the grim hallmarks of US drone tactics in Pakistan.

Earlier this year the Bureau exposed a CIA practice of ‘follow-up’ strikes in an investigation with the Sunday Times. On at least a dozen occasions twin strikes killed at least 50 civilians. The civilians died when they rushed to help victims of an initial attack and were hit by a second, follow-up strike.
