New Delhi, May 31 (IANS) The Communist Party of India-Marxist (CPI-M) Monday urged the government to condemn the Israeli attack on a flotilla of six ships carrying humanitarian aid to Gaza.

‘India must also work actively with other countries from the non-aligned nations in the UN and other bodies to force Israel to lift the illegal siege of Gaza,’ the CPI-M said in a statement.

The statement said Israeli armed forces ‘illegally attacked’ the flotilla in international waters Sunday night, killing at least 15 international activists and injuring many.

About 700 activists from a number of countries were on the six ships aiming to take 10,000 tonnes of humanitarian aid to Gaza, ‘which has been under relentless siege for almost three years now’.

‘The attack … shows the complete contempt Israel has for international law or international opinion. Attacking ships in international waters and killing its passengers is a brazen act of piracy,’ it said.
