PARIS—The son of Libyan leader Moammar Gadhafi is warning the Western powers currently bombarding his country that they could become a target if they continue to support the forces trying to oust his father.

In an interview on French television, Seif al-Islam Gadhafi also said Libya is ready to call a cease-fire, adopt a new constitution and hold democratic elections.

But he warned that, by supporting the Libyan opposition, Western countries “are going to be a reasonable target for us.”

In a separate newspaper interview published Monday, he said Libya is “ready to put in place a transition government” for three or four months.

A coalition including France, Britain and the United States are striking Gadhafi’s forces under a U.N. resolution to protect civilians.
