Benghazi attack faces US Congress committee scrutiny

Security in Libya was complex and ever-changing in the run-up to a deadly attack on the US consulate in Benghazi, a US panel has heard.

A former US Army officer, Lt Col Andrew Wood, told the hearing that security "remained a struggle" and was weak until he left Libya in August.

Debate centred on whether the state department's security chief sought more security staff to protect US diplomats.

Republicans have criticised the Obama administration over the incident.
