Prime Minister David Cameron has said the UK is not ruling
out providing arms to rebels in "certain circumstances" but no
decision has yet been taken.
The idea has met with opposition in the House of Commons,
where shadow foreign secretary Douglas Alexander questioned the legality and
"advisability" of such a move.
The rebels are continuing to lose ground to forces loyal to
Colonel Gaddafi and are retreating from their former strongholds along the
eastern coast of Libya.
