Ireland will mount its biggest security operation to welcome Britain’s Queen Elizabeth II and US President Barack Obama in the space of a week.
Militant groups opposed to Britain’s control of Northern Ireland are the biggest risk during the queen’s four-day visit.
“We know her majesty is welcome in this country,” Superintendent John Gilligan told a news conference. “Unfortunately in this country still we have a threat posed by dissident republicans,” he said. “The gardai [police] are prepared if necessary to deal with any issue that may arise.”
Surveillance has been increased on suspected dissident republicans and al-Qaeda sympathizers, some of whom have been arrested and questioned. Police have sealed inspection covers in roads and combed central Dublin, where much the queen’s visit will be focused.
Up to 5,000 police officers, backed by 2,000 soldiers and with support from the navy and airforce, will provide security during the monarch’s visit.
Adding to the security headache is the arrival of British Prime Minister David Cameron for the state dinner in the queen’s honor at Dublin Castle on Wednesday. On the same evening, the UEFA Europa League final will be held in Dublin between Portuguese teams Porto and Benfica.
The threat from dissident nationalists in Northern Ireland is the highest since a 1998 peace deal ended a violent campaign by the Irish Republican Army.
A protest is planned outside Dublin’s Garden of Remembrance, a memorial to Irish people who died fighting for independence from Britain, which the queen will visit, as well as on the evening of the state banquet.
Three days after the departure of the queen, Obama will arrive to meet the Irish president and prime minister and visit the County Offaly town of Moneygall from where one of his ancestors emigrated in the 1800s.

US secret service agents have vetted Moneygall, whose near 300 inhabitants are delighted at the prospect of welcoming their “most famous son.”
