The bloodshed spiked ahead of a major NATO operation in the Taleban's southern heartland. US commanders have warned of more casualties as the alliance gears up to clear Kandahar, the biggest city in Afghanistan's south and the former headquarters of the Taleban.
NATO announced the three deaths Tuesday without identifying nationalities. But US and British authorities provided the nationalities of the victims, all of whom died in the south.
The deaths took NATO's death toll in June to 24, including 14 Americans, according to a count by The Associated Press based on official announcements.
Monday was the deadliest day of the year for the international force in Afghanistan with 10 deaths, including seven Americans, two Australians and one French Legionnaire. They were killed in five separate insurgent attacks in the south and east of the country. Two civilian contractors training police, an American and a Nepalese, also died in a suicide attack Monday in Kandahar city.
Afghan officials said two other battles raged overnight between Afghan and NATO forces, in the provinces of Kandahar and Badghis in the northwest. No NATO casualties were reported.
The range of attacks served as a grim reminder the insurgents can strike throughout the country — not simply in the south, which has become the main focus of the US-led campaign.
US President Barack Obama in December ordered 30,000 more US troops to Afghanistan to try to stem the rise of the Taleban, who have bounced back since they were ousted from power in the 2001 US-led invasion.
In the northern city of Mazar-e-Sharif, more than 1,000 people shouted "Death to America, Long Live Islam!" and burned an effigy of the pope in an angry demonstration against alleged Christian proselytizing in Afghanistan.
Afghan authorities on May 31 suspended operations of Church World Service, based in Elkhart, Indiana, and Norwegian Church Aid pending an investigation of allegations carried in an Afghan television report. Both charities deny spreading Christianity.
Mohammad Hashim Mayar, deputy director of the Afghan group that coordinates nongovernment organizations in the country, said officials at the intelligence service that is conducting the investigation told him Tuesday it was yet to be completed.
"We are waiting for the results impatiently," Mayar told AP Television News. "If we do not know the final result, the situation will get worse and the security of the expatriate and national workers of the NGOs will be endangered." In Badghis, Afghan special forces backed by US
helicopter gunships battled insurgents for 12 hours overnight Monday in a remote Taleban-controlled region, killing 23 militants, said the commander, Maj. Zainudin Sharifi.
And Kandahar's provincial government said in a statement Tuesday that Afghan and NATO troops had battled Taleban militants in the Mianshen district, killing 14 insurgents.
The Interior Ministry said seven Afghan private security guards were killed two separate attacks in eastern Ghazni province.
As fighting escalates, the Afghan government is reaching out to the insurgents in hopes of ending the war.
Last week, President Hamid Karzai won endorsement from a national conference for his plan to offer incentives to the militants to lay down their arms, and to seek talks with the Taleban leadership. The leadership has so far publicly shunned the offer, and the US is skeptical whether peace can succeed until the Taleban are weakened on the battlefield.
