A French father who wants visiting rights with his young son is spending a fourth day protesting atop a crane, but says he'll consider coming down after France's justice minister agreed to meet with a fathers' activist group.

Justice Minister Christiane Taubira is scheduled to meet Monday afternoon with SOS Papa. The divorced man on the crane in the eastern city of Nantes, Serge Charnay, wants France to strengthen its law on shared custody. He was convicted of taking his son on an unauthorized vacation for two months in 2011, and said he regretted nothing because "if I hadn't I wouldn't have seen him."

Another father with similar grievances briefly occupied a crane in the eastern city of Strasbourg over the weekend before police persuaded him to come down.
