At least 25 militants with suspected links to Al-Qaida have been arrested in connection with the deadly attack on the US Embassy in the Yemeni capital, a senior security official said on Thursday.
The Yemeni official said the 25 have been rounded up from various parts of Yemen over the past 24 hours and were being questioned by Yemeni and US investigators.
It is not unusual for authorities in Yemen, a key partner in the US-led war on terror but for years an al-Qaida stronghold, to round up a large number of suspects in the wake of a terror attack.
The official, speaking on condition of anonymity because he is not authorized to speak to the media, said a US team, possibly from the Federal Bureau of Investigation, was on its way to Yemen to take charge of the investigation.
US Embassy spokesman Ryan Gliha would only say that it is "standard procedure" to dispatch an FBI team in cases of attacks against US interests abroad.
The attack Wednesday killed 16 people but failed to breach the compound's walls.
