ATHENS, Greece — A protest by migrants detained at a facility northeast of Athens because they entered the country illegally has ended and the detainees have returned to their rooms, police said Sunday.
Officers on motorbikes continued to comb the surrounding area for escapees but there were no signs of a breach at the detention center itself, according to a police announcement. There are about 1,700 migrants at the facility.
The protest started when some detainees attacked guards at nightfall Saturday as dinner was being served. According to police, the attack on the guards was unprovoked. The detainees also set fire to their bedding and some of the containers that housed them.
Police said at least 10 prison guards were injured, none of them seriously. It was not clear if any detainees were injured.
Shortly after midnight, riot police entered the camp and used chemicals and stun grenades to quell the protest. About an hour later, detainees had returned to their rooms.
Police said that the main cause for the protest was the announcement to the detainees that maximum detention time at the camp was to be increased from 12 to 18 months. Also, electricity had been cut due to maintenance work, leaving the containers without air conditioning.
Detainees have often complained about conditions at the camp, including overcrowding, with some staging a hunger strike earlier this month.
The camp is one of several around Greece, officially called "closed hospitality centers." At the end of their detention, the undocumented migrants are deported, or, more rarely, freed and granted asylum.
