PLO and Hamas trade gunfire back and forth, to and fro

It should be clear that a civil war is indeed breaking out between the PLO and Hamas. For starters, a Hamas minister's convoy was attacked:

GAZA CITY, Gaza Strip - Gunmen attacked the convoy of the Palestinian foreign minister and raided a training base for an elite security forces unit Sunday, stepping up factional violence over a decision by Palestinian President Mahmoud Abbas to end nine months of Hamas leadership and call early elections.

A 19-year-old woman and a Palestinian security officer were killed in the chaos, while at least 13 people were wounded in gun battles across Gaza City. In one symbolic attack, Abbas' empty residence came under fire. Militants also fired two mortar shells at Abbas' nearby offices.

And then, mortar shells were fired at Mahmoud Abbas' office:

GAZA (Reuters) - Gunmen fired two mortar bombs at Palestinian President Mahmoud Abbas's office in Gaza on Sunday, wounding at least five members of his personal guard as tensions with the ruling Hamas movement threatened to boil over.

Foreign Minister Mahmoud al-Zahar, a senior Hamas leader, accused Abbas's forces of attempting a "military coup" in Gaza after they overran two ministries under the control of the Islamists. Zahar demanded the security men leave the ministries or else be arrested, a move that could provoke further violence.

"What is happening is a real military coup, assassinations, attempted assassinations, the occupation of headquarters and ministries," Zahar told a news conference.

No, what is happening is a terrorist gang war, between two Islamic terror gangs, both of them evil, and both of them power-hungry. It shouldn't be surprising that is where things led to, and now, they're both at each others throats.
