A school partially collapsed in the Haitian capital on Wednesday, injuring at least five students less than a week after the collapse of another school killed 89 people.

Portions of the Grace Divine school in Port-au-Prince came crashing down while class was in session. As word of the incident spread, crowds of anxious parents descended along with ambulances and crews from the collapse of the College La Promesse in nearby Petionville.

No one was trapped inside and there were no deaths.

Five students were treated for injuries, the most serious of which was a broken leg, said Jean-Fetner Frederic, administrator of the nearby Canape Vert Hospital.

Two other students at another school in the area suffered minor injuries when hundreds of parents rushed the building based on a false rumor that it had collapsed, Frederic said.

Earlier, Edouard Ernseau, a city building inspector who was at the scene of the Grace Divine collapse, said two students were injured and seven people outside the school were injured.

The cause of the incident was unknown, though Ernseau said recent heavy rains may have weakened the two-story concrete structure.

On Saturday, Haitian President Rene Preval said poor construction, including a lack of steel reinforcement, was to blame for the collapse of College La Promesse the day before. He warned that many other buildings throughout Haiti are in danger of failing and he called for greater oversight.
