Violent clashes in Yemen

British and American ships and submarines have fired more than 110 cruise missiles at over 20 targets in Libya, targetting air defence systems and fuel depots near Tripoli.
British aircraft have also entered Libyan airspace in what has been baptised Operation Odyessy Dawn. Earlier in the day the French said one of their planes had knocked out four tanks near Benghazi.
Thousands of Libyans have formed a “human shield” around Colonel Gaddafi’s compound in the capital to protect it from air attack.

The French carried out wide ranging aerial reconnaissance missions across Libya all afternoon ahead of the evening bombardment. They also patrolled the skies above Benghazi in an attempt to halt operations by Gaddafi loyalists. The city was under heavy bombardment all day.
Coalition navies, including Canadian vessels, are now in position to blockade Libya, enforcing a ban on arms sales to the Libyan government.
