GAZA CITY, Gaza Strip ? Dozens of disgruntled Palestinian police officers stormed the parliament building Monday, complaining they do not have enough firepower to confront Hamas, and legislators upset over the growing chaos demanded that Palestinian leader Mahmoud Abbas reshuffle the Cabinet and fire his security chief.

The protest and parliament’s rebuke of Abbas came a day after the worst fighting between Hamas and police in nearly a decade. Three people were killed, including the deputy police chief in the Shati refugee camp near Gaza City, who was shot in the head after he and his men ran out of bullets during a Hamas assault on their station.

After the most recent onslaught on his security forces, Abbas said Monday he would stand firm.

However, Palestinian security officials say police are no match for the armed groups.

In Gaza, only about half of the 18,000 members of the security forces carry guns, with a limited number of bullets at their disposal, the officials say. Hamas in Gaza commands at least 5,000 gunmen, according to some estimates.

During the police protest, the Palestinian parliament was holding an emergency session on the growing lawlessness.

In a 43-5 vote, legislators asked Abbas to present a new Cabinet within two weeks, and many demanded the ouster of Interior Minister Nasser Yousef, who oversees the security forces.
