A Muslim mob recently burned a Catholic church in Sudan's capital city of Khartoum -- continuing violence as a result of hostilities between Sudan and South Sudan.
The church is built on land the two nations are disputing.
South Sudanese living in Khartoum worshipped at the church and witnesses say hundreds of Muslims shouted insults at the southerners before setting the building on fire.
On the same day, warplanes of Khartoum's Islamic regime dropped bombs near a major town in South Sudan, killing a young boy and wounding several others.
As violence continues, human rights groups and international leaders are concerned of the possibility of war.
CBN News Sr. International Correspondent Gary Lane talked more about the hostility between Sudan and South Sudan. Click play for his comments from the April 27 edition of Christian World News.
The bombing came hours after Sudanese armed forces launched an attack more than six miles inside South Sudan's border. The attacks come just days after the south announced it was pulling its troops from a disputed border town to avoid an all-out war between the two neighbors.
Maj. Gen. Mac Paul, deputy director of military intelligence for South Sudan, said that two MiG 29 jets belonging to Sudan dropped three bombs, one of which exploded in Rubkona market, a major population area.
"The bombing amounts to a declaration of war," Gen. Paul said.
Sudan and South Sudan have been drawing closer to war in recent months over the sharing of oil revenues and a disputed border.
Paul said late Sunday that South Sudan was building up its forces because they think Sudan is also doing the same.
U.S. and international observers fear the two sides are inching towards open warfare.
South Sudan broke away from Sudan in July last year after an independence vote, the culmination of a 2005 peace treaty that ended decades of war that killed more than 2 million people.
Despite the treaty, violence between the two countries has been on the rise.
The Arabic Islamic regime of Omar al-Bashir in Khartoum has targeted the people of the south for religious and ethnic reasons. Most southerners are black Africans and follow Christianity or traditional African religions.
