ISMAILIA, Egypt, April 17 (Reuters) - Egyptian police shot dead an Eritrean migrant on Thursday as he tried to slip across the frontier into Israel, bringing to 11 the number of migrants killed at the border this year, security sources said. The sources said two other migrants, from Eritrea and Sudan, were shot and wounded in the same incident when police opened fire on a group of migrants who disregarded orders to stop. All three migrants were men in their 20s and 30s, the sources said. Violence against migrants at the border has escalated since the start of the year, with police killing 11 and detaining scores of others, mostly from Africa.
Rights group Amnesty International has called for an investigation into the killings and says Israel has pressed Egypt to reduce the flow of people crossing illegally.
The London-based rights group says thousands of migrants try to cross from Egypt's Sinai peninsula each year, with numbers rising since 2007.
The migrants, including many from Sudan and a growing number from Eritrea, are seeking work or asylum away from conflict at home and harsh living conditions in Egypt, where activists say African migrants face economic marginalisation and racism.
