French higher parliament house approved Monday night to prolong the full-pension age regardless of contribution period to 67 instead of present 65.

With 174 votes for and 159 against, the important article of the controversial pension reform bill succeed to make headway by push of the UMP-led right-wing senators, while the left-wing parties, including the Socialist Party, unanimously voted against the bill.

The senators also approved two amendments promoted by Sarkozy government favoring French parents with handicapped children or mother who has three children in a way to mitigate public outrage toward the reform.

The adjusted clause allows parents with handicapped children and mother with three children to retain the rights to full pension entitlement at the retirement of 65, disregarding their contribution period.

French trade unions is preparing to show the government their utmost rage with a new round of general strike and country-wide demonstration on Tuesday.

Railway unions even vowed their strike to be open-ended while ports workers' walkout in southern France cities are entering the 16th day.

A recent poll after the previous mass demonstration on October 2 showed that most of the strikers didn't believed in persuading the government to drop the reform while persisting in hope of making lawmakers do more modifications.
