US State Department asking for more funds to beef up security at overseas embassies, missions

The US State Department will seek billions of dollars in new funds to revamp security procedures around the globe

It's doing so in response to criticism by an independent commission investigating the attack on the US mission in the Libyan city of Benghazi

The assault killed US Ambassador to Libya Christopher Stevens and three other Americans.

US Secretary of State Hillary Clinton's two top deputies appeared at a Senate hearing and conceded that officials had failed to "connect the dots" ahead of the attack

Mrs Clinton was unable to appear at the hearing due to illness

Her office said she has already asked for 1.4 billion US dollars in funds for the 2013 fiscal year to be re-allocated to improve security at US diplomatic missions.

Senate Foreign Relations Committee Chairman John Kerry chaired the session and led the call for increased funding:

"We need to make certain that we are not penny wise and pound foolish when it comes to supporting America's vital interest overseas."

Mr Kerry is tipped to be US President Barack Obama's pick to replace Mrs Clinton as Secretary of State when she steps down next month
