Libyan rebels run to take cover as mortars from Moammar Gadhafi's forces are fired on them.

LONDON -- Britain says it will supply communications equipment to Libyan rebels as they battle Moammar Gadhafi's forces.

Foreign Secretary William Hague told the House of Commons that the equipment "will help with the protection of civilian lives and the delivery of humanitarian aid."

Hague also said that the United Nations and the European Union may consider dropping sanctions against some members of Gadhafi's regime if they abandon their support for the Libyan dictator. But he insisted no member of Gadhafi's inner circle would be offered immunity from prosecution for past crimes.

Hague confirmed that British officials have encouraged former Libyan foreign minister Moussa Koussa to answer questions from Scottish police and prosecutors over the 1988 Lockerbie airline bombing. Koussa fled Tripoli for Britain last week.
