SANA'A — Dozens of police soldiers stormed the Interior Ministry building in Sana'a on Sunday, forcing road blockages leading to the ministry building.

A security source who is not authorized to speak with the press said sporadic clashes took place throughout the day between police soldiers, protesting against the ministry, and soldiers working under Minister of Interior Abdul-Qader Qahtan during his presence in his office.

The source, who was also one of the protesters, said nobody was killed or injured during the all-day stand-off, pointing out that the soldiers on both sides were firing their weapons in the air.

"After the clashes, the soldiers were able to take over the ministry building and close it down," the source said. "For two months, we've been demanding our allowances without success, so we resorted to taking over the building to put pressure on the ministry to pay us our allowances."

At the main gate of the ministry building, protesters held banners that read, "Our Minister of Interior … where are our period allowances" and "No for intolerance and partisanship ... we're the sons of one country."

In addition to the police soldiers' demands for their allowances, they also called for the ministry to increase their salaries, to provide them with health insurance, and to be eligible to gain fair promotions.

Dozens of armed civilian men were deployed near the ministry, blocking the roads and preventing people and cars from approaching the ministry building.
