BEIJING -- Terrorists following a call to violence by the Islamic State (IS) militant group staged three high-profile bloddy terrorist attacks in different parts of the world in just one single day on Friday, killing and woulding dozens of innocent people.

The bloodiest of the attacks in the day took place in the Tunisian resort of Sousse when an armed young man, disguised as a tourist, pulled a Kalashnikov from a beach umbrella and sprayed gunfire at a group of sunbathers, mostly Europeans, killing 38 people.

It was the worst attack in Tunisia's modern history and the second most serious massacre so far this year following the IS militant assault on Tunis Bardo museum when gunmen killed 21 foreigners in March.

Almost at the same time, 25 people were killed and at least 202 others were wounded in a suicide bomb strike on a Shiite Muslim mosque in Kuwait. The IS has claimed responsibility for the attack.

It was the first suicide bombing at a Shiite mosque in Kuwait and worst militant attack in the country for many years. However, it was not the first time for the IS group to plot such attacks against mosques. It has also claimed responsibility for bombings at two different Shiite mosques in neighboring Saudi Arabia in recent weeks.

On March 20, IS suicide bombers attacked two mosques in Yemen's capital Sanaa and Houthi headquarters in the northern Saada province, killing at least 137 people, in the most deadliest attacks in Yemen for decades.

In France, which has experienced a slew of terror attacks in January this year which started with a deadly assault on the French satirical magazine Charlie Hebdo, a victim was decapitated in a US-owned factory, with a flag of Islamic State aside.
