Global Terror Watch after Deadly Bombings in Pakistan

A global terror watch is in effect after yet another deadly terror attack. This latest one took place on Easter Sunday in Pakistan.

The death toll from the massive suicide bombing has climbed to more than 70, with at least 300 wounded as the country begins observing a three-day mourning period.

"We are really, really sad and feeling so upset because it is a day of our worship," Minister of Ports and Shipping Kamran Michael said.

A Taliban faction claimed responsibility for Sunday's bombing targeting Christians, including children celebrating on rides at a park in the eastern Pakistani city of Lahore.

Riots erupted for a second day in Islamabad, Pakistan's capital. Extremists, who have been staging a protest since Sunday, surged toward the parliament and other key buildings in the city center.

Daud Sharif, with the Pakistan Christian Congress in Punjab, told CBN News the Christian community is in deep grief over the Easter attacks. Click play to hear his suggestions on how the global Christian community can help:

The violence was condemned on social media.

"Get hold of the culprits and make an example of them. Enough of this madness in the name of love," Facebook user Karami Elahi wrote.

Sunday's attack comes nearly a week after devastating suicide bomb attacks in Brussels, where the airport is only beginning to test its capacity to partially resume passenger service.

As Belgium continues to mourn the dead and injured from Tuesday's terror attacks, violence erupted at the memorial site where police broke up protests by nationalists angry at Muslims.

"Everyone that's not Belgian -- because this is Belgium -- if you don't want to live like us, go," one resident said.

Meanwhile, European authorities are still trying to track down those responsible for the mass casualty attacks.

They arrested a man in Italy whom they believe forged documents for terrorists in Brussels and Paris. Police in Holland arrested a French man for planning an attack.

And across Belgium, nine people have been detained after more than a dozen raids. Authorities say they have evidence ISIS may have also been plotting to strike a nuclear plant in Belgium.

Meanwhile, the U.S. State Department has now confirmed that four Americans are among the victims killed in the Belgium bombings. They include the young couple Justin and Stephanie Shults.

"Stephanie had a very strong belief in God, and Stephanie is in heaven," her aunt, Betty Newsom, said.

The string of attacks has the world on a higher terror alert. This weekend, troops with automatic weapons could be found outside Notre Dame Cathedral in Paris and in Saint Peter's Square in Rome.
