Dozens of protesters were injured, six of them shot by government troops, in one of the entrances of Sana'a change square when troops attacked them Saturday morning.

More than seven massive explosions were heard in Yemen's capital during the early hours of the day.

This is considered the first time troops try to forcefully enter and attack youth at Change Square since June.

In the fiercest morning of clashes in more than three months, clashes intensified

in the Hasaba zone of Sana'a between government troops and tribal fighters loyal to Sheikh Sadeq Ahmar, the tribal chief of Hashed tribe.
