No, it has to do with politics. It also has to do with the presence of foreign rogues and rascals, who invaded Iraq under lies and deceit in Iraq and are currently in Afghanistan. They are the ones, who pitted the Muslims against each others.Pakistan militants kill 40 in mass execution, attack on Shiites
QUETTA, Pakistan - Pakistani militants, who have escalated attacks in recent weeks, killed at least 40 people in two separate incidents, officials said on Sunday, challenging assertions that military offensives have broken the back of hardline Islamist groups.
A car bomb exploded near a convoy of buses taking Shiite pilgrims to Iran, killing at least 19 people and wounding 30, officials told NBC News, the latest attack on the minority sect.
Earlier Sunday, 21 tribal policemen believed to have been kidnapped by the Taliban were found shot dead in Pakistan's troubled northwest tribal region, government officials said.
Witnesses said the blast occurred as the three buses were overtaking a car about 35 miles west of Quetta, capital of sparsely populated Baluchistan province, site of many sectarian attacks, near the Iranian border.
Pakistan has experienced a spike in killings over the last year by radical Sunni Muslims targeting Shiites who they consider heretics. The violence has been especially pronounced in Baluchistan province, where the latest attack occurred.
IOW, it's "good" Muslims muredering "bad" Muslims "For Allah and His Messenger."
There were no sectarian clashes in Iraq before the US invasion, at all.
Anyway, one reaps what one sows, so we have to live with it. Let them kill each other. You should be happy as along as they do not kill your folks at home, foreign troops in Afghanistan excluded.
"My enemy's friend is my enemy" is the main reason. Pakistan is suffering from this foreign instituted cancer. All Muslims taking the sides with the Americans and the Nato, are getting it.
