LONDON: British Prime Minister Theresa May vowed on Monday to fight terrorism in all its forms after awhite driverploughed his van into a crowd of Muslims, injuring 10 people.

It was the fourth terrorist strike, in a tumultuous four months in Britain, which took place in the early hours of Monday after prayers in a mosque in Finsbury Park in north London.

One man also died at the scene after falling ill for unrelated reasons just before the attacker struck.

Ms May condemned the assault as `sickening`, saying Britain`s determination to fight `terrorism, extremism and hatred... must bethe same, whoever is responsible`.

The 48-year-old van driver was detained by people at the scene before being arrested on suspicion of attempted murder.

The Finsbury Park Mosque said the van `deliberately mowed downMuslim men and women leaving lateeveningprayers`atthemosque and the nearby Muslim Welfare House shortly af ter midnight.

Many linked the attack to an increase in anti-Muslim hate crimes, particularly since a van and knife rampage in the capital on June 3 that left eight peopledead, which was claimed by the militant Islamic State group.

Increased police presence London police chief Cressida Dick said the incident was `quite clearly an attack on Muslims` and promised a stepped-up police presence near mosques as the holy month of Ramazan draws to a close.

The attack unfolded as an elderly man was receiving first aid from members of the public in an unrelated incident.

The man later died, though it is not yet clear whether his death was linked to the attack, said Neil Basu, the police senior national counterterrorism coordinator.

Witness Abdigadir Warra said the van `drove at people` and that some of the victims were carried for several metres along the road. `He was shouting: `All Muslims, I want to kill all Muslims`,` another witness, Khalid Amin, told BBC.

Ten people were hurt, all Muslims, with eight requiring hospital treatment.

Two were in a very serious condition, police said.

Mr Basu praised locals for detaining the man, saying their `restraint in the circumstances wascommendable`.

France and Germany quickly condemned the attack and Egypt`s Al-Azhar University condemned it as `sinful` and urged western countries to take steps against Islamophobia.

Mohammed Kozbar, chairman of the Finsbury Park Mosque, described the attack as `cowardly`. `Our community is in shock,` he said, urging people attending prayers to remain vigilant.-AFP
