Ceasefire in pieces after day of violence

The five-month-old Middle East ceasefire appeared to be unravelling as Israeli strikes on a van filled with rockets and a West Bank hideout killed six Hamas militants following a Palestinian rocket barrage on an Israeli town and a suicide bombing that killed six.

In an effort to stop the rocket fire, Palestinian police fought Hamas gunmen in a daylight gun battle in the streets of Gaza City that left two teens dead and 25 others wounded in the worst internal fighting among Palestinians in recent years.
