Update: New anti-govt group, ‘walla3,’ claims responsibility for Giza bombing

A group called "Walla3" has claimed responsibility for the Friday morning bombing of a police checkpoint in Giza.

Around 2 pm, the group posted on their official Facebook page that the attack was the first in a series of actions they would take against "the deep state." 

Walla3 defines itself as an anti-government group that has no political or religious affiliations.

Around 10 am on Friday morning, two explosive devices detonated near the Giza bridge, reportedly injuring four security personnel, according to a Ministry of Interior statement.

The Health Ministry reported six were injured, according to the state-owned Middle East News Agency (MENA).

The police checkpoint that was targeted in the attack was recently established near the Istiqama Mosque, the site of repeated protests and clashes since the January 25, 2011 revolution.

A Mada Masr reporter was passing by the area at the time of the explosion.

“[I] was passing by Giza Square and we heard a large thud, and then people ran. There were two police or CSF [Central Security Forces] vans on the overpass, and some broken glass,” the reporter said.

The Interior Ministry said explosives experts and civil protection forces were sent to the site of the explosion, and that the injured were transferred to the hospital for treatment.

Security forces were inspecting the area, but as of early Friday afternoon did not have details about the circumstances surrounding the attack.

Over the past few months, a series of bomb attacks has targeted police stations, checkpoints and other facilities around the country.
