The picture emerging of the perpetrators of Sunday's attacks that killed more than 350 people is one of relative privilege. The country's defense minister says one bomber had studied in the U.K.

Officials have been altering names to become more Hinducentric. "It is very dangerous for national integrity and unity," says a historian. The changes accelerated ahead of this year's elections.

In 1992, Hindu extremists tore down a 16th century mosque, igniting Hindu-Muslim riots that killed thousands. India's Hindu nationalist ruling party wants a temple to a god built on the ruins.

Here are some key things to know about Sunday's deadly attacks, the group that Sri Lanka blames for perpetrating them — and the country's complicated history.

Sri Lanka is blaming a Muslim militant group for the Easter attacks that left nearly 300 dead and wounded 500 others. The nation has a complex ethnic and religious tapestry and a history of conflict.

Government officials in Sri Lanka say that a little-known Islamist extremist group is responsible for the Easter Sunday attacks that killed almost 300 people. No group has claimed responsibility.

As India's economy has opened and grown robustly, so has Hindu pride. A lifetime after India cast off colonial rule, it's embracing a new identity and its majority Hindu faith is playing a big part.

More than 200 people were killed in a series of attacks on Sri Lankan churches and hotels on Sunday.

At least 130 people have been killed in coordinated bombings in Sri Lanka that targeted luxury hotels and churches, as people gathered for Easter services.

The country's oldest private airline once boasted the largest fleet in the subcontinent. But it lost altitude in recent years amid fierce competition from regional low-cost carriers.

Many see India's election as a turning point in which the country may seek to redefine itself via Hinduism, its majority faith. Secularism has become "a four-letter word," says one expert.

The world's biggest election is underway in India. Polls opened Thursday, with five weeks of voting. Vendors are cashing in with election-themed fashion, including saris with the prime minister's face.

Polls have opened in 18 Indian states and two union territories. It is the first day of a seven-phase election staggered over more than five weeks in the country of 1.3 billion people.

April 13 marks 100 years since one of the worst massacres of the British Empire, when soldiers killed hundreds of unarmed civilians at Jallianwala Bagh in Amritsar.

Kashmir, disputed between India and Pakistan, is the site of a decades-long insurgency. It is also a winter sports haven. During recent airstrikes and shelling, a ski station remained open.

The pilot was captured this week after his MiG-21 fighter jet was shot down over the Pakistani-administered part of disputed Kashmir.

The move is seen as an attempt to step back from the brink of war between the nuclear rivals. However, Pakistan's Prime Minister Imran Khan warned that the gesture should not be seen as "weakness."

Both sides claim to have shot down the others' warplanes in what amounts to a major escalation of tensions between the rival nuclear powers.

Pakistan says it shot down 2 Indian planes inside its airspace and launched strikes on Indian-controlled Kashmir. Tuesday, India said its fighter jets killed terrorists at a training camp in Pakistan.
